My Green Mattress

My Green Mattress was founded with the mission to create an all-natural mattress that wouldn't harm those that are sensitive to off-gassing or other forms of toxicity in and around mattresses. From their family-owned factory, they offer a variety of Dunlop latex and pocket coil mattresses for both adults and children that are Greenguard, GOLS, and GOTS certified, which are some of the highest organic and safe certifications out there. Their mattresses get high marks from most customers and should be on your shortlist if you are looking at eco-friendly and all-natural options.

Novaform

Novaform mattresses are well known for being sold in Costco warehouse locations. Owned by memory foam developer and manufacturer Innocor, nearly all of the mattresses sold by Novaform are memory foam mattresses. Also found at popular retailers like BJ's and Sam's Club, Novaform's product offering and quality differs slightly per retailer. However, overall, with a variety of mattresses in different thickness options, Novaform gets some good initial feedback from customers. Still, there are some reported issues with heat retention, firmness, and initial comfort in some cases.

Based on our aggregated reviews and our scoring method, we recommend My Green Mattress in this match up!

My Green Mattress's Owner Satisfaction

We all want to get a sense of which mattresses are best rated by sleepers, but it is not always that clear when browsing online. Sleepers are highly satisfied with these mattresses overall based on the data we analyzed across the net. Although you not have the same great feelings towards this brand after buying, a great customer satisfaction score is a good starting point.


My Green Mattress's Supportiveness

Mattress support is the secret to waking up refreshed in the morning. You want a mattress that supports your health rather than causes you nightly aches. Customers report that these mattresses support the spine well.

Edge Support
Edge support is really important for those that like to dangle their feet over the side of the mattress. These mattresses are good at edge support and don't feel much different than in the center of the mattress.

Bowling Ball & Density Tests
A popular test for reviewers, the bowling ball test gives a good reading on mattress firmness and evenness of support. If a mattress doesn't have even response, then there is a big problem. However, these mattresses do a good job providing even support for sleepers.


My Green Mattress's Durability

Durability is the single most important criteria for buying a new mattress next to initial comfort. Getting up to a decade of use out of a mattress is well rated in terms of longevity. However, some of the things that could affect durability are material quality and sleeper size. Reviewers give these mattresses good marks for durability versus others. However, some that are heavier may see a slight decrease in durability.

Novaform's Owner Satisfaction

Figuring out the takeaways from customers can be a great eye-opener for shoppers. Customers don't always respond well to these mattresses. Some feel snug and comfortable, but others feel discomfort. There are more details below to study if you are considering buying.


Novaform's Supportiveness

Some customers have been satisfied with the supportiveness of these mattresses, but some others have been dissatisfied. For those with achy backs that need spine alignment, make sure to do additional reviews before buying.

Edge Support
Reviewers have mixed concerns about edge support. Some folks have reported good amounts of comfort throughout the mattress, but others had issues with supportive comfort and changes in support.


Novaform's Durability

Customers find that durability is one of the most important attributes to finding a mattress. We all wish our mattress will last a decade or more and still provide us with cozy comfort. Unfortunately, not all customers regard these mattresses highly overall on durability, and some have had some problems over the short term. If you are considering buying for your main mattress, read the reviews to make sure that it will match your body type before buying.

GREAT mattress at a TOTAL STEAL
I cannot rave about this mattress enough -- very comfortable, non-toxic materials I can feel good about (and I am very picky about everything I buy in terms of toxicity), and what a total STEAL! I had been searching for mattresses for ages, and I could not find anything I wanted for a price I could afford until I came across this one. No off-gassing, but there is a very faint, not-at-all-unpleasant, earthy smell to it. And it was delivered very fast, way before the promised time frame. Lastly, the mattress was not nearly as uncomfortably hard/firm as some of the reviews indicated. I actually wish I had not bought the expensive latex topper I already purchased elsewhere, because it really doesn't even need it. I was a little nervous about buying a mattress online, but I am SO happy with this purchase.

Incredible Bed at an incredible price
My wife is a Naturopathic Doctor and understands the importance of a natural mattress and insisted we buy one for my daughter when we moved her out of her crib. I was hesitant since these are so expensive, but she explained that sleeping on a mattress that is not natural means that her face is pressed up against chemicals and toxic off-gassing for an entire night. This was a huge concern so we searched high and low for a high quality natural mattress that would also provide her with a good night's sleep. We went to a local store that specialized in organic mattresses and could not find anything that felt good (they felt flimsy) and they were all so expensive. I decided to search online to see if I could find something and luckily I found the Echo Mattress.

We purchased the single sided Echo Mattress for my little girl and we absolutely LOVE it. It is super clean, no smells at all, and very comfortable. It came packaged rolled up and was super easy to bring upstairs and unroll onto her bed.

Now when I read my little girl bedtime stories I end up staying in bed with her a bit longer than I need to so I can enjoy her comfortable bed. I was actually enjoying my little girl's mattress better than my own so we decided to buy a King Size double sided version of this mattress for my own bed.

This is an incredible bed an a wonderful price and the customer service in this place is amazing too!

Really REALLY firm. Took some time to adjust.
When I started waking up with back pain on my 8 year old Beautyrest mattress, I knew it was time to get a replacement. I wanted a 'natural' mattress that was free of flame-retardants and off-gassing chemicals, but most of them were way out of my price range. I found this one on Amazon and read all the reviews. Something to note: at the time of this writing, there are currently 18 reviews with an average 4 1/2 star rating. However, half of those reviewers specifically say that they purchased this mattress for a young child so they are not reviewing it from an adult's comfort perspective. I'm going to tell you right now, this mattress is firm. Very firm. Another reviewer likened it to sleeping on a bed of rocks, which is not far off. I would say it's more like sleeping on a carpeted floor. When I first started sleeping on it, I was very disappointed--it was so uncomfortable. I should add that I have a 2 inch latex topper AND a featherbed on top of it, and it's still ridiculously firm. However, after sleeping on it for seven weeks, I have gotten used to it. I am no longer waking up with back pain and I'm not breathing in toxic chemicals. Taking into consideration price, convenience (free ship/rolled up), and natural components, I would say that I am happy with the purchase. Just know that you're going to have to put some sort of topper on this mattress--I can't imagine any adult being able to sleep on this with no cushion.

good value for the quality
The mattress arrived quickly and in good condition. We did not have any problem with the firmness, and thought it was comfortable support. My problem was with the mattress fibers/ stuffing. We let it air out for a week before putting in on the bed. Although my spouse did not notice any smell, the mattress did give me a stuffy nose every time I laid in it for about a month, even after changing out the mattress pad and sheets. This finally went away after a few weeks and I am able to enjoy the mattress now.

Amazing value for your money!
We were looking for a healthy alternative to our other mattress that wouldn't break the bank and would be better on our backs. We had looked at other organic mattress that were 6 times this cost so when I found this one I was estatic. This mattress has far exceeded our expectations. It is so comfortable and we don't wake up in the morning with terrible neck and back pain. Some people have complained about how hard it is, however we never experienced that. I do enjoy sleeping on the ground from time to time as it helps my back feel better so I am used to firm sleeping spaces. At first, when you open it and unroll it or does have a strong wool smell but it's nothing obnoxious and it does go away in a couple days. We have been sleeping on this mattress now for a couple months and have felt the improvement and I love knowing there's no off gassing and I sleep easier. I would highly recommend this product for anyone looking for a more budget friendly organic mattress!

Wanted to like it, but ultimately just uncomfortable even with toppers
I really, really wanted to like this mattress. We are very careful with the products we buy, to make sure everything is healthy and get the best for ourselves and our kids. I got this mattress in King for myself and husband, and 2 Twins for my kids. I knew it was going to be firm, but damn! It's just not comfortable. I wanted to like it, I really did- tried everything, spent more money on toppers than I ever imagined I would. I got a very fluffy lofty topper, it didn't help. I got a wool topper, still nothing. I had a firm before, but this mattress is TOO firm, I sleep on my side and have curves, it just puts pressure on my joints. Now I'm stuck and unhappy. The kids are light weight, and I got them toppers too for added comfort, but due to how they sleep- it seems to be ok for them. As for me, I'm wishing we didn't get rid of our memory foam mattress which was a lot more comfortable. We only got rid of it because we wanted to clear the house of toxins. I really, really miss that mattress. Can't afford another topper to try, or a new mattress at this time.

Three Stars
too firm for our taste

Like it but cant get rid of smell for month
Like it but cant get rid of smell for month. Waiting for summer to put it on a direct sun again

LOVE IT
What can I say, I LOVE this mattress ! It's firm without being hard.

AMAZING. This mattress came in a roll and so ...
AMAZING. This mattress came in a roll and so was really easy to maneuver onto the bed and then cut open. It is soo comfortable our daughter loves it.

I simply would not purchase another one like this.
I did not realize when I purchased this mattress that it is only 'one sided' but unfortunately it is and it is extremely hard. I simply would not purchase another one like this.

Sweet, non toxic dreams!!
I don't write reviews, but we bought this mattress for our daughter and she has slept so soundly on it! Knowing what we do about off gassing and what conventional mattresses do to our bodies, we knew we had to go with this company and ultimately this mattress! Thanks again for your stellar product!

Regarding Smell
I was a little concerned about all of the reports of the smell of the mattress. When we unpacked it I didn't smell anything but when I put my nose right against the mattress and inhaled I could smell a very tiny smell that my son said reminded him of Play doh. I think it's actually the smell of the plastic that the mattress came in. If I had not been looking for the smell I would not have noticed anything at all.

Seems like a safe and comfortable option
This was just delivered today so I will update later. The box was quite beat up, but the mattress inside was clean (wrapped in plastic). Upon opening and unrolling there was no chemical smell: one person said 'it smells like granola' and another person said 'it smells healthy'. Three adults (of very different sizes and weights) each lay down on it (separately lol) and each found it comfortable. It is medium firmness, not hard.

most comfortable bed in our house
most comfortable bed in our house. my father in law now kicks my son out of his bed when he visits

This is the most comfortable mattress I remember ever sleeping on
This is the most comfortable mattress I remember ever sleeping on. I was sure after reading previous reviews that I would need to purchase a topper to make it more comfortable, but I love it just the way it is. I sleep better than I have in years.

Great mattress
My spouse and I love this mattress. We've had it for about 5 months now and sleep very well on it. It's not too firm but firm enough that it won't give you back problems. It did smell a bit like wool or barn when we first got it but too the mattress' defense, I was in my first trimester of pregnancy so everything smelled to me. I aired it out in the sun for two days as the company advised and it really did help. I feel really good knowing that I sleep on a healthy mattress. I plan on buying another one.

Great mattress and excellent price!
We were looking for an organic mattress, and this one was an excellent price. That being the case, I was not expecting to find such high quality! I am very happy with this mattress! It is very firm, which I like because it has really helped my children's back issues to be sleeping on a firm mattress, yet it is still comfortable. It seems sturdy, well-made, and I have high hopes it will hold up well as my children grow up. It had no odors other than the cardboard and exterior packaging, arrived quickly and was packed all rolled-up- so it was very compact and relatively easy to transport, considering it is a mattress! I was so pleased with the purchase of the first mattress for my son that we have purchased a second for my littlest, who sleeps much better now that she is on this mattress, interestingly enough. I highly recommend this mattress and will be purchasing a third mattress after the baby on the way is big enough for a bed. Many thanks to the company for offering a quality product that is free from chemicals, well-made, and very reasonably priced.

Probably wouldn't buy again.
We purchased two of these mattresses in the twin size for our four year olds. They are not super comfortable but our children seem to like them. I probably wouldn't buy them again but time will tell how well they hold up.

Matress is firm
Matress comes rolled up and pops out like a roll of biscuits !!! Places a matress topper on it and it is money !!! Very happy with the purchase

Love it. I bought another after the first one ...
Love it. I bought another after the first one came in, very comfortable!

Five Stars
This mattress is better than I expected!

Chemical smell
t smells gross, with a really strong chemical smell that comes through the bedding even six months later. I am worried about having my child sleep on it and am considering throwing it out. I don't know what the smell is but it can't be anything good. I should have known that the price was too good to be true.

Great Mattress. Worth Every Penny
I needed a mattress that wouldn't make me swell up from all the chemicals on it. So many were expensive or didn't look very comfortable. I eventually took my chances on this one. I was concerned about the mention of smell because I am very sensitive to smells. I even called the company to ask if they could air the mattress out for a few days for me. I wasn't patient enough to wait the first time for them to answer because I needed a mattress soon but an unfortunate event turned into a fortunate result. When the bed arrived, FedEx had an accident with the package and the bed was no longer sealed inside the packaging. I called the company and sent them pictures. I called FedEx and they picked up the mattress. The mattress company remembered me and before getting the mattress back, they started airing a mattress out for the 3 days that other reviews mentioned. They sent the mattress to me before even getting the mattress back. BTW, the smell reminds me of Cheerios in case you wonder what it smells like. This mattress was just made right before it was sent to me so it is very understandable I could still smell a little of the materials. I have had it for less than a month and I sleep well. I don't wake up swollen. I am so happy about that. I have arthritis and I wake up stiff most of the time with the old mattress. I barely ever have problems with this new mattress. I got organic sheets too. The bed is firm, very firm. I like soft beds but the firmness doesn't bother me at all. The bed is wool and cotton. There isn't foam so there isn't much to make it fluffy but I figured if I had a problem, I would get a mattress topper. I don't need one though. I am quite comfy in this bed. This is a great mattress with great employees. I would highly recommend buying one.

The bed is perfect medium
The bed is perfect medium firm and very comfortable. It does not have any odors and delivery was fast. Highly recommend.

I switched to this mattress
I switched to this mattress after sleeping on a premium organic latex mattress from another company that cost nearly $3000 and sank terribly in the middle after only a handful of years of use. The Natural Escape feels extremely high-end in its materials and construction, and I adore the perfect medium-firm density. Such a reasonable price point for the unquestionable quality (not to mention the fab company philosophy!) I now own two�one for me and one for my toddler son.

Easy setup
Easy setup

Very comfortable without the sunk
Very comfortable without the sunk in feeling of memory foam, great edge support and I didn't feel hot like with some mattresses. Outstanding customer support that handled everything quickly and professionally.

This is the most comfortable
This is the most comfortable mattress I�ve ever owned! Customer service was very helpful and nice, and it didn�t smell at all when I unpacked it. Would highly recommend!

Great organic mattress
I’m chemically sensitive and have bought three of these mattresses in the last two years. I love them.

So far so good!
We’ve only been using it a week but I’m happy so far. My hip pain more or less went away after the first night!

Comfortable, natural mattress!
My family and I were in the market for a non-toxic mattress. We had been doing a lot of research because we have a new baby. We compared options and we came across Mygreen. We were skeptical about a mail ordered mattress. But, we have been pleasantly surprised by this wonderful mattress. It has a lower price point than other natural options. No adhesives. Non-toxic materials. It is very comfortable. It has very faint earthy smell to it. I will recommend this company to all of my mommy friends and family. We love it! Thank you for a healthy nights rest!!

Best mattress I have ever owned
This is the best mattress I have ever owned and has given me the best sleep of life over the past three years (and still going strong). My wife and I are about to buy our second for a guest room.

Love this mattress. I salute
Love this mattress. I salute with the middle of five, the other chemical bed mattress companies along with the satanic government agencies that mandate the use of chemical fire retardants. Because you never know when you might spontaneously combust into flames during your sleep. In any case, this mattress is amazing. And not being forced to sleep on cancer causing chemicals is well worth the price.

I researched organic mattresses for
I researched organic mattresses for weeks prior to purchase. My Green Mattress was the Best Buy based on price and comfort for combo sleepers like my husband and I. We also bought the topper for additional softness. We are very happy with purchase. Highly recommend.

Our whole family loves how
Our whole family loves how soft and firm this is, depending on your perspective! We even changed over from memory foam topping over our last bed, and found this mattress to be a downright good quality bed. I personally love the intention of the company and the �cleaner� product compared to other beds/companies! Would definitely buy again!

Nice mattress! We like that
Nice mattress! We like that the quality and safe materials this mattress is made of. There were no smells upon opening the box. The price isn�t cheap, but we are happy with the product. It is firm, but our backs feel good!

We've been sleeping on this
We've been sleeping on this mattress for a couple of weeks or so. My spouse says it's "fine", and a great improvement over our previous, worn-out foam pad. I've had serious back troubles all my adult life, and am utterly delighted with it so far. I was waking up every morning with a lot of back pain, all gone now. I really hope this mattress continues to work this well!

My husband and I absolutely
My husband and I absolutely love this mattress! We love how it feels but most importantly we love the quality of it. We sleep better just knowing it does not contain harmful materials and its all natural. Great costumer service and fast delivery. Worth every penny!

Huge fan of this mattress!
Huge fan of this mattress! Easy to put on my frame and fits perfectly! I love how comfy it is!

Good if willing to put a few extra bucks into it
Pros: Price, shipping, delivery, ease of getting into bed room, highly rated by consumer reports
Cons: Firmness is mislabeled, requires a memory foam topper to be comfortable

I did a lot of research before buying our new mattress. We had never done a memory foam mattress before and thought we would give it a try. We went to a department store and tried out their memory foam beds to make sure we thought we might like it and picked the right firmness.

I have traveled for a job and stayed in nice and bad hotels. I thought I was pretty experienced to differ mattresses and comfort levels. This one is rated medium firmness, I would say it is medium firm to firm. It is much firmer than any mattress I have slept on. I could see how it could be firmer so I won't say it should be rated firm, but it is at minimum medium firm. There is no feeling of memory foam. There is almost no give in the mattress. You expect a memory foam mattress to give to your body a little and you fit into it. This does not happen with this mattress. I was excited to see what the pearl gel memory foam felt like. There is no indication of pearls, gel, or memory foam on the top layer.

Awesome
After researching mattresses for months and with great fear I ordered this matress based on Costco's return policy, consumer reports rating, and customer reviews. It arrived by courier ( He even dollied it into our bedroom )! It unpacked as it should. No smell , no waiting - we slept on it that night. I had left the board that I had been using on the box springs but after a 2 weeks removed it because I read that it should not be used on the floor but on box springs. It went from firm to medium and viola. Perfect!!! I've had the matress over two months and purchased gel pillows. Honestly, I've never had anything this comfortable. The gel pillows work in sync with the matress. It's NEVER hot. But now that it's winter it's not cold either. I'm just in awe when I lay down at night and even more pleased when I wake up. Great job Novaform. Great Job Costco! My first purchase from your company has made me a life long customer.

Great Mattress and Price but too firm
I have had this mattress for @ 2 years. I think it will probably last forever, but it is NOT medium in firmness. I would say at least medium firm +. You do not sink in as you do on most memory foam mattresses, but surprisingly I do sleep very well on it. It really doesn't feel like a memory foam mattress. Seems good for both side and back sleepers. I do wish it was a little softer. Slept on a water bed with 'pillow top for years until the bladders could no longer be patched. They don't make water bed mattresses like this anymore (solid pillow top and sides that drop over base and bladders. Probably this was the most comfortable mattress I've every had. Unless you like a soft mattress you will be very happy with the Serifina' and at $650 ($799 Cal King which I have)nothing else comes close.

Bought it, returned it, opted for diff product
Lesson learned- don't skimp on a mattress you spend 7-8 hours using and if you have back/neck problems. Wife and I bought this and gave it a ride for 30 days. Felt it was too soft, did not hold form. Returned it after 30 days. It came in a box the size of a dorm room fridge. That should probably be a characteristic of caution in the first place. Might be suitable product for college kid looking for something that can ship easy. Not a great solution for neck/back problems.

Deserves 10 stars!
For years we wanted a Tempurpedic so when Costco.com offered them a couple of months ago, we took the plunge. For six weeks, I did not sleep. The Tempurpedic was hot, hard as a brick, and uncomfortable. It was also excessively tall.

We returned it and replaced it with the Serafina Pearl Gel Mattress. Oh. My. Gosh. It is like sleeping on a cloud. I like a softer mattress while my husband prefers a firm mattress. We are both happy and are sleeping through the night with no tossing or turning. Do not hesitate to get this mattress!

Too Firm
Costco service and delivery and price were all great. I just could not stand this bed. It was not medium. It was very firm. Felt like concrete. I switched to the Valentina and I love it.

Too Hard
I bought this mattress a month ago and haven't gotten use to it yet. Will probably send back. Will maybe try the more expensive softer mattress.

Extremely comfortable
Having had a 15 year old firm mattress the change to this memory foam mattress its everything I had hoped it would be. Sleep on both side and back, both very relaxing and comfortable.

Great mattress
We needed a new mattress, so I researched them starting with Consumer Reports, which rated this their top foam mattress. This is our first foam, so I really didn't know what to expect. Also, we have never purchased a mattress without first trying it out in a store. It arrived quickly and was fascinating watching it expand after to cut the plastic off it. I have to say that it's harder than I expected, but I am getting used to it after two weeks. My wife, who sleeps on her back, is sleeping noticeable better. There's also no movement transferred to the other person, which is a good thing. Neither of us noticed any unpleasant smell as some have reported.

HORRID!!!!
Relying on the glowing review in Consumer Reports, I purchased this mattress more than two months ago and believed the enclosures that said it could take a while for the mattress to fully set. Well, sufficient time has elapsed and it is still the most uncomfortable mattress I have ever slept on. (It replaced a 16- year-old mattress but thank goodness I hung on to that one because I plan to put it back on my bed and give this mattress away.) The mattress is so hard, I wake up with a backache every morning and my Activity Tracker shows I am having very restless nights. I actually have to fold up several blankets and use them as padding under me because the mattress is so hard and uncomfortable. I would not even call it 'firm,' it is the hardest mattress I have owned and I always buy firm models to provide more back support. Worst money I ever spent!

Great Mattress!!
I researched alot of mattresses on their comfort, side and back sleeping and reviews and price. This one came out on top. We used to have a waterbed and thought it would be difficult to adopt our lifestyle to a regular bed. We got flannel sheets and have slept like a baby ever since. It's hard getting out of bed in the morning. Very nice.

Great Bed, Great Price
I bought this bed in February 2016 and like the other reviews found it very hard. After about 2 months, it become much more comfortable. I love it now, find it very comfortable, doesn't make my back hurt and I would certainly buy it again. You have to give it a few months and then it's great. If you are looking for a pillow top snuggly bed, this is not for you.

Great Mattress
We bought this a month ago and cannot be more satisfied. We did think it was slightly more fim then we expected but after 2 nights of sleeping we realized it was a medium firmness. The most comfortable mattress ever. Havent slept this well in years.

Perfect for me
1. I read all the reviews on the COSTCO, other sites and checked consumers overall this bed seemed to be a good choice as far as quality. 2. As you can see from the reviews some people say this bed is to hard, some say it is to soft and others say it is just right. Depending on your weight depends on how much you 'sink' into any mattress that also effects how hard of soft the mattress 'feels'. 3. I enjoy a 'firm' mattress in which I do not sink a lot into it but I do expect it to conform to my body this mattress works perfectly form me. 4. Smell: Upon delivery I set up the mattress and aired it out for about 6 hours. I then put on a mattress pad and bedding. The only way to smell anything unusual was to put your nose to the mattress and that lasted about 2 days. 5. Price: After checking warranty and cost this bed via COSTCO gave me the best value.

Very firm
I did hours upon hours of research and thinking before deciding on this mattress I read every review posted. How firm a mattress feels is different for everyone so how can you yourself decide until you have one.? I needed a firm mattress for my back issues. This one was rated so well and it was a no risk purchase. I decided to give it a try. I am a woman approx. 130 pounds. My weight didn't put a dent in it anywhere! I felt like I was laying on top of it with little to no give at all. It also took a couple of days to expand to be able to press a hand impression into it. It did not get hot, The smell of it was minimal, it is very heavy, easy set up and this is an good quality mattress. I was hoping it would conform to my body a little but it didn't. For me, it's as firm as any Firm mattress without plush or a pillow top I've tried out there. The medium firmness rating doesn't feel accurate for me or my weight at least. It's harder than the highly rated Se@ly kelburn also recommended by CR. Hope that helps as a way to compare for you. Love Costco and always will!

Novaform @costco review
If you've owned a high end pillowtop mattress you will not be satisfied with this bed, If you haven't its perhaps doable, For the money right aroud 600 dollars its worth the money, It actually helped my wifes back, And she woke up without her usual discomfort, For me it felt to firm and lacked that luxurious feel and its not something i can imagine spending 1/3 OF MY LIFE ON FOR THE NEXT 10 YEARS, That being said again its still worth the money.

Promising
We have tried a number of the Novaform mattresses. Each one seemed to have great promise but fell just short. We love the affordability and potential of the mattresses. Our first Novaform serafina pearl gel memory was too soft (rated in top 4 on CR), but nice if you like plush. We then tried the Novaform firm memory foam, which was firm and comfortable but retained so much heat that I was waking at night changing shirts from sweat. And finally the serafina pearl firm with gel, once again too soft. I must admit, I have had lower back problems, so I look for firm to extra firm mattresses. For now, we are giving up on foam mattresses.

Provides support and gently hugs you
I've been sleeping on this mattress for a few weeks now and find it to be comfortable. The mattress is softer than I prefer with a very plush top layer that hugs your body and offers support (at the lower back). You do sink into the mattress a bit which can slow you down when changing sleep positions. Before this mattress, I slept on a foam mattress - it retained heat but I feel this mattress retains more heat. My spouse really likes this mattress though. There isn't any edge support. There is an off-gasing smell that lasted up to 48 hours after unpacking. Overall: nice support, a little too soft, retains heat but I like it.

Not Supportive
At first we thought this mattress would work for us, but after a week we knew it wasn't supportive enough. We are 60 and 59, 230 and 130 lbs respectively. I am a side and back sleeper, my husband a side and stomach sleeper. I noticed that the mattress didn't hug my lumbar region while sleeping on my back. I could feel a gap there and there shouldn't be. My husband thought it was too squishy, not firm enough. What we both disliked is that the sides cave in when sitting on the edge of the bed, so you basically slide off. We had to return it and we are now trying a Sterns and Foster pillow top firm. Back to basics for us.

The best purchase ever!
We were moving to Ireland and wanted to buy new beds for everyone but we had a budget as moving countries is expensive. We gone One queen and the kids got full size each. I was very nervous as we would not be getting to try them untill we were in Ireland. However, I need not have worried. They were the best purchase ever! I normally have back issues and have never woke up even once with stifness or soreness in my back. Still totally love this bed after nearly 10 months. My only issue is now when I visit friends or stay overninght else where, the beds seem completely sub standard.

Firm cradling comfort
My husband and I bought this to replace our 7 year old tempurpedic. This Novaform 14" Serafina is the most comfortable mattress my husband and I have ever slept on. That includes all mattress's at hotels, friends' and that we've owned. We're in the mid 50 to early 60's age range. It gives a firm but soft cradling support and is not hot like our previous memory foam. We read reviews in Consumer Reports and this met our budget and was one of the top rated mattress's. We got it on sale and is a great value even at full price. Highly recommend!!

Takes getting use to.
We purchased this mattress last year for a vacation cottage. We allowed it to sit opened on the bed overnight before we slept on it. We own a pillow top mattress at our home, so this was our first Memory Foam mattress and we purchased this based on good reviews and the price. The first few night we slept terrible! We both woke up sore each morning. After about 5 nights we finally started sleeping better. I do find it to be hot, especially if you are sleeping on your back. It is soft on the top, but very firm underneath so you have good support. We are going to buy a mattress topper to try and soften it even more to what we are used to sleeping on. Overall for the price it is a good mattress, but does take time to get use to.

More of a medium firm
I love having a king bed, it is lovely! First time trying out a memory foam mattress. My husbands only request was to get a firm mattress. I would say its more of a medium-firm. You do sink in a little right away. I woke up the first week with sore back, which I never have before on my other spring mattress, but I haven't recently, so I am wondering if my body had to first get used to it. I also am 19 weeks pregnant, which could have been part of it, or that the first week we didnt have a platform for it yet!! Me or my husband havent had any issues with overheating on it like I read in some of the reviews.

Great mattress
This was a first....after shopping all over for a firm mattress, (costs were &1200-$4800+). Reviewed Consumer Reports, this mattress was very highly rated and less than $1000. Then it went on sale in February!!! With Costco's return policy we decided to give it a try. Then we learned it would be coming in a box!!! A king mattress in a box!!??!! When it arrived...in a box...flat as a pancake...there was no way this was going to work.....wrong....within three hours this 'pancake' turned into a full size king extra firm mattress!!! No more tossing and turning it's the best nights sleep we've had in a very long time...granted, it's only been a week...but so far so good. Would and have recommended this mattress to everyone we know.

Excellent !
I researched mattress online. This one came in the top 10 at number 5 . I bought this mattress 3 months ago. I always had a coil mattress and needed a change. I knew I could return it if I was not happy. Costco is great to deal with if there is a issue. It is the best mattress I have ever slept on. Extremely comfortable, not hot, my back even feels better. My wife feels the same way and she was really concerned. She is not tossed around when I move or turn over.

Firm was better than medium firm
We tried both the firm and the medium firm version of this mattress. The medium firm was available in warehouse and the firm only available online. My wife chose the firm version do to less motion transfer and no sag/roll toward the center due to my laying in the bed. She was able to get rid of a boomerang pillow she previously needed for side sleep with our Sleep Number bed that we got rid of. It took about two hours, a roll of heavy duty packaging tape, clamps, 2x4's, and a vacuum to get the medium firm mattress small enough to return to Costco...but they did take it back.

Too Soft for Us
Frankly, my one star is probably unfair, but if you love a very hard innerspring, as my husband and I do, do not be lured in by the "firm" label. That's firm for a foam mattress, not firm for a mattress in general. We sunk into it as if it were a marshmallow. In fact, after trying it for a few nearly sleepless nights, we dragged our old rock-hard innerspring mattress onto our bedroom floor and there until we were able to lift it off our bed and arrange to return it to Costco. We are SO thankful for Costco's return policy. I cannot imagine sleeping on this huge marshmallow for another night.

Disappointed
We bought the mattress online through Costco only because they don't carry California Kings in the warehouse. It two weeks to get it. Unpacking it was not to difficult. It's been a week since we've had it and the mattress still hasn't fully reached its full shape. The bottom right side is still smashed. As for comfort, the only option was to go with firm in a cal king. It's like sleeping on flat mat, there is no give, no comfy feeling. I can't seem to find a comfortable position and my lower back is achy in the morning. Will give it one more week like the instructions recommend but doubt very seriously I will keep it. Not at all what I hoped it would be, the delivery time, the shape not right and the total lack of comfort, especially for the money.

Life Changing
My only regret is not buying one sooner! I'm so glad that I took the time to go lay on a few different beds first. I even got fitted by one of those computer beds that measure all your pressure points to figure out how firm of a bed you need. Being a big guy (6' 300lbs) I'm so glad I went with the firm Serafina. You do sink in a lil little, but only really enough to form to your body. I have nothing bad to say about this bed and would recommend it to anyone.

Finally a FIRM comfortable bed.
Many thanks to Costco for their return policy. This is the second mattress I have purchased from Costco in the last six months. It is quite firm which is what I needed. The first purchase seemed fine for about two weeks, but then the "sleep impression" began to appear...sort of like a troth.

I was hesitant about buying
I was hesitant about buying and surprised to receive it in a box, but what a great mattress. I am 6'4" 320lb and the firm is surprisingly comfortable for me and my 5'3" 123lb wife, We love it. A !2" mattress might have been better, our deep sheets are not deep enough for the 14" mattress

Great Bed
I bought this bed a couple of months ago and love it. It’s the perfect firmness. It’s very similar to the Tempurpedic medium firm and softer than the Sleep Science Black Diamond. I’m a side sleeper and it does not hurt my shoulder like the SS Black Diamond did. This bed is an incredible value, especially when it’s on sale. I highly recommend it if you have laid on the Tempurpedic medium firm and like that firmness level.

Serafina Ordered Accidently...
So we ordered a "bed-in-a-box" from Costco, thinking we had ordered the King sized Novaform Comfort Grande. Shortly after receiving an email confirmation, the email read "Serafina Pearl." Initially, i was scrambling through different websites to see a comparison of the 2 beds. The Comfort Grande was said to be less firm than the Serafina Pearl. I was thinking that the Serafina may be too firm as the Comfort Grande eluded to the fact that it too was a firm bed. Now that I have received the mattress and have slept on it for a couple weeks now, I am so happy that we stuck with our accidental purchase of the Serafina Pearl. The mattress has the perfect amount of firmness that my wife and I prefer. Also, the king size makes this bed even more amazing as we often share it with our 2 kids and a 70 lb dog.

Perfect Amount of firmness
Let me start this review by saying that everyone is different. Back problems run in my family. I am only 26 and I have back issues already. I workout, I stretch, I walk, I do yoga, but all of that won't matter unless I have a quality mattress. I tried an online mattress company, and it was super comfortable, but made my back pain worse because it was too soft. This is the perfect amount of firmness. Give it a few weeks as you would with any mattress. Your body may be sore because it needs to adjust to a new mattress. This was well worth the money and provides great support. The only con I can think of is the weight. It will be tough to move. But it is worth it!

My only problem...
My only problem is that there appears to be no way to determine before you purchase what firm means when comparing foam mattresses of different companies. Our first firm memory foam mattress from Costco was 7-8 heard old and finally lost its rebound. Our new foam mattress labeled firm is as soft as our sagging old memory foam mattress. Is possible it was mislabeled? Thanks for listening. W F Bolin

Heat - Heat - Heat!
Mattress gave off unbearable heat. Not sticky, sweaty heat - just steady, intense heat. Impossible for me to sleep. For ages, at home, hotels, friends' homes, I fell asleep very quickly after laying down - usually 1-5 minutes. With this mattress, if I was lucky, I'd finally fall asleep 90 minutes after laying down. Then I'd wake up every 60-90 minutes because I needed to sit up or turn to let my back cool off. (I normally sleep like a rock!) Tried for over 2 weeks thinking maybe it would ease. Extreme disappointment as quality otherwise seemed good. Minimal odor - way less than expected. Pretty firm but not overly. But the heat was crazy horrible. Had to return.

SOFT & HORRIBLE
I just bought this mattress less than 1 week ago. I desperately needed a firm mattress following a recent bad back injury. This mattress is NOT FIRM BY ANY MEANS!!!! You sink down into it, and it's difficult to get back out of bed. The sides cave in when you sit on the side of the bed.

Best Mattress Ever!
This is hands-down the best mattress that we've ever owned! We were a little hesitant to purchase a foam mattress, having heard stories of how hot they were to sleep on and how hard it was to move in the bed. However, we have experienced neither problem. The bed is not hot and neither of us have experienced any problems moving on the mattress. We both sleep better than we ever did on more expensive mattresses and for the first time in many years, I have no back stiffness when I wake. We bought the mattress to replace a Sealy hybrid that was only 3 years old but it was no longer comfortable to sleep on. I highly recommend this mattress.

An awesome bed!
My wife and I have had our bed for about 3 weeks now and we couldn't be happier! This mattress is top quality and is amazingly comfortable. No more neck, back and hip pain. Couldn't be more pleased with our purchase. This bed is "bang for the buck". Our last bed we purchased 10 years ago and paid 4 times as much. Our new mattress is so much more comfortable and the rest we get is incomparable. Highly recommend! Two thumbs up!!

DO NOT HESITATE TO BUY
My wife and I bought a Simmons BeautyRest Mattress two years ago for $1800. After 6 months our spine/hip health started decline. Going to orthopedics etc and spending money that wasn’t necessary to find out after buying this Novaform mattress, our 2 year old mattress was the cause of ALL of our issues. We got the firm mattress and it’s the most amazing sleep we’ve had in forever. Do not hesitate to buy this mattress. For $800, it saved our hip and spine health. Do NOT get caught up in the lies of mattress store prices or sales people.
