Comfort Tech's Specifics

Comfort Tech mattresses are popularly sold at Costco and other major retailers. When it comes to their mattresses, their mattresses feature all-foam designs with two layers of foam. With options in both firm and medium, most average sized sleepers can find something that is comfortable for them, but there are some complaints about sagging reported on these models.

Those that are concerned about durability and long term comfort, take a look at our top rated mattresses for great alternatives. Specifically, our list of the best memory foam mattresses provides strong alternatives to these beds.

Craftsmanship & Quality

Comfort Tech has two mattress options, the Serene and the Aurora mattresses.

We'll go through each of their mattress options in depth below:

Here are the details about the Comfort Tech Serene Mattresses:

The Comfort Tech Serene mattresses come in two firmness options -- firm and medium. There are two layers of foam on these mattresses, 2'' of contouring Serene™ foam cradles the body and 8'' of high density foam provides back support. While most customers like these mattresses at first, there are some that experienced quick sagging issues with these mattresses.

Next, here are the details of the Comfort Tech Elite Aurora Mattress:

The Comfort Tech Aurora mattresses are 12'' high and only come in medium firmness. There are three layers of foam on this mattress. A softer 1'' Aurora foam, followed by 3'' of pressure relieving Serene™ Foam, and 8'' of supportive base foam. Most customers find this mattress comfortable and quite pressure relieving. However, there were many who found them not supportive enough for them with some reporting issues with discomfort.

Last, here are the details of the Comfort Tech Intuition Mattress:

The Comfort Tech Intuition Mattress offers an all foam design that features airy memory foam for added temperature regulation and cooling. The three foam layers offer medium firm with pressure relief and spine support balance. Customers have good things to say about the Intuition overall, but there were some that describe lack of support and smell in some cases.

Overall Comfort

These mattresses get mixed reviews when it comes to comfort. Some find initial comfort to be ok, but others had issues with sinking in too far in some mattresses. Others had issues with degrading comfort over time.


See the above scale. While most describe Comfort Tech's firmness reliable at first, there are some that described degrading firmness over time.

Back Pain Relief

Due to some sleepers describing these mattresses to be too soft and having issues with keeping supportive over time, some may experience issues with back pain discomfort.


Some disagreements about these mattresses include issues with them keeping cool. Some have described heat retention in these mattresses.

Who Are Comfort Tech Mattresses Right For?

These mattresses are best served as temporary options as there are some disagreements with long term comfort. For those looking for quality alternatives, take a look at our top rated mattresses for strong alternatives.

The price is right!

After being deeply disappointed in an overpriced Beautyrest mattress we thought we would try a memory foam as these seem to be the highest rated and with $100. off the price, it was worth a try. It was (surprisingly) firm to us, a little too firm. The next night I put a 3 inch memory foam topper ( already had it) on and it is perfect for us now. Our previous mattress had sagged after a few months and the manufacturer replaced it as guaranteed, but only with the same exact mattress! What is the use of that?? At least if this happens I have Costco's return policy and it was only $400 bucks not $2000. So far so good. I will follow up in two months.

Exactly what we were looking for, comfort like no other twin mattress.

We bought queen size Comfort Tech 10'' Serene Performance Foam mattress about eight months ago. It is very comfortable and feels almost soft to the touch but once you lay down on it it cradles your body without sinking into a hole. The Medium density description fits the bill. My husband is 6' and weighs 170 lb and I am 5'4'' and weigh 120 lb. Also I don't sweat at night which I used to on our previous foam mattress. The only small minus is that the edges are softer than on our older mattress which might be an issue for some people.

Good Sleep

I bought this mattress for based on 2 reasons, price and reviews. Having never slept on a foam mattress, I was skeptical about this purchase. I decided that based on the price ($350 on sale) it was worth a try. After the first night I knew I had a winner. Two months of use and I am still waking up feeling rested. As a side sleeper, my arm and hips no longer ache in the morning. As a tummy sleeper, my wife's back doesn't ache in the morning either. We couldn't be happier. So glad that we didn't spend hundreds more for a traditional spring bed.

Love this mattress!

We bought this mattress several months ago, after researching mattresses for far too long! Desperate for a new mattress, and overwhelmed by the information and options available, we decided that this one was so inexpensive, it wouldn't be a risk to just buy it. We were unhappy with the uneven wear of traditional springs. Nor did we care for the 'stuck' feeling of memory foam. This mattress is a joy to sleep on! It is supportive and cushioning. I disagree with the review that says it holds the impression of your body. Ours does not do that at all. It is absolutely nothing like the memory foam mattresses we slept on in the past.

My new favorite mattress!

The great reviews for this mattress gave me the courage to order it sight unseen and I'm so happy I did/ Shipping took a little longer than expected but customer service was great. I don't know if I would have bought this if I'd just sat down on it in a store as it feels really firm at first and my last mattress was a pillowtop. With that being said, I love this. I can toss and turn in bed and not wake up my husband. I don't wake up with any aches or kinks in my body. Normal sheet sets fit it perfectly. When it was hot, I didn't feel like the mattress was guarding any of our body heat. I will definitely be replacing future mattresses in our house with this brand and buying one for the travel trailer! Warning: Definitely do not open the plastic wrap until you have the mattress in the room where you want it. That sucker just swells right up and it's harder to move because it doesn't have the traditional binding/edges like other mattresses.

feels just right

I was skeptical because of the price but we loved it from the first night! More comfortable than our Temper-Pedic

Great buy for the price

Bought this mattress based on my friend's recommendation and the reviews here. It came in a small box and came to full size once opened. It had a chemical smell for the first 2-3 days but disappeared eventually. It is medium as listed, not firm. It sinks when you sit on it, but when you sleep you won't sink and feel relaxed. When you press it, it reacts lot quicker than a memory foam mattress, so you change positions easily. The mattress is great for side, back or stomach sleepers. We have been using it since 2 weeks. We are loving it and are having sound sleep every night. It doesn't feel hot when I sleep on it. We tried many mattress at stores and were skeptical to buy online. I thought of giving a try before buying at store, because of Costco's great return policy, but I wanna keep it since it's great and cheaper. I recommend this product. It's a genuine review and I was not paid to write this.

We have had this mattress

We have had this mattress for a little over a year and both my side and my husbands side of the bed have sunken in. This has caused the middle of the mattress to be higher than the sides so if you try to lay near the middle, you feel yourself rolling towards the edge of the bed. Also, though they say this mattress is Medium firmness, we would say it's slightly more on the soft side. Would not recommend this at all. I hope to be able to return this, but not sure if I can since we've had it for a year.

Great at first... 1 year 5 months later...

Bought this mattress Feb 2016, it was awesome at first. Agree with most reviews on quality of sleep but not so much on firmness. So if you sit at the edge of the mattress you will squish it all the way down. If you kneel on it, your knees will sink all the way down. But when you lay on it, weather on your back, stomach or side, the mattress will distribute your weight evenly and hugging you confortably for a great nite of sleep. It is truly amazing!!! I sleep in all 3 positions. On my old mattress if on my side, I'd wake up with aching hips and shoulders. Not on this mattress though. Instant relief very first night. It is now July 2017, and for the past 6 months I'd say, this mattress does NOT feel like it did at first. I rotated it according to instructions. But it's just not the same. According to the manufacturer description, it will feel softer as it ages. My wife and I however come to the conclusion the opposite is happening. The mattress feel as it gotten harder. It no longer conforms to our bodies giving us that even weight distribution I first described. And I am starting to pick up on pressure point when I sleep on my side. Wife and I have contacted Costco to arrange return. Haven't decided if will simply exchange for same model or get a refund and try different brand. Oh, also it claims to be cool, but it is not. We found it to be quite warm.

Great for a while..

I have had this mattress for 8 months. I would say the first 5 months it was great! However, after waking with terrible back pain, I noticed how bad it was sagging. I tried several toppers and pads and it just didn't help. I always turned the mattress (it can't be flipped) and still didn't help. Could be good for an occasional guest bed, but not for everyday sleeping. I have to start the mattress search over again...

Comfortable memory foam

If you like memory foam in general, this mattress feels soft and relieves pressure. I would rate it about a 5 on the firmness level, with 10 being the highest. So it is a little softer than some other leading brands, which was a plus for me. If you are not sure about the idea of Serene Foam vs memory definitely feels like memory foam. It leaves the classic indentation where you have just been lying. People that are used to memory foam will most likely love it, if they like a plush feel. I, however am not and didn't like feeling stuck. I used Costco's return policy with absolutely no problems. They did just what their policy stated they would do.


We were hesitant to buy a foam mattress. This one sleeps cool, very comfortable. Didn’t find it overly soft, it’s a medium support in my opinion. Unwraps and fills quickly. No odor.


We bought this for our toddler who was moving into a twin bed. It is so, so comfortable. He loves it-along with everyone else in the house! Mattress was easy to unpackage and was ready to go in moments after expanding. Would highly recommend-such a great price! Would certainly purchase another when needed!

Mattress is okay but...

We purchased two Twin XL a couple of months ago for our adjustable twin frames. They are supposed to be medium firm but would have to disagree and lean towards soft. As of yet I have not noticed any defects and I will have to take a closer look and report back. The mattress is too soft so not sure what I will do.

Good buy

Very comfortable. Great price

comfort plus

I bought this mattress for my 15 year old grandson. He absolutely loves this thing!! He said he is sleeping so much better, and he wanted us to come over and try it ourselves. He was right. It is extremely comfortable.

Perfect fit!

My husband and I bought this mattress 1 momyhsgo after sleeping on the same one in a spare bedroom at my friends house. It’s the perfect mix of firm with some give. First time my husband and I have been able to agree on a mattress!

Great value

I bought the Serene Medium foam mattress a few months ago, after I moved into a new house, for the guest room. I had originally bought an I-comfort mattress and box springs for my master bedroom at a furniture store and could not get a full night sleep on it. This mattress cost one third of what I paid for the one in my room and it is just so much more comfortable that I have moved it into my room and the guests will have to make do with the other one. The Comfort Tech was advertised as not too firm and not too soft. In a few words, it is Just Right.

Feels firm, yet comfortable.

We bought this for my son. It is firmly supportive and he loves it. I was thinking about purchasing the firm mattress for my husband and me, but the medium is firm enough. I have sat on it and it doesn't sink, or leave a lasting imprint. My injured tailbone wasn't bothered. We highly recommend this mattress.

Good mattress

Very happy with the mattress, process and delivery.

Great rest!

I bought this abut a month ago for my son, he loves it!

Firm but not hard

I love this mattress. It's firm but not hard or uncomfortable.

We received our comfort tech

We received our comfort tech on December 8th, and have had the best nights sleep ever. The quality and comfort of this mattress goes without saying. We are full time RVers and travel a lot so a good night sleep is extremely important. All we say is this is the best mattress we have ever owned.

Bought it for my son

Bought it for my son. So far he is happy with it. He said it keeps him cool around his body. So, he sleeps well.

Very Comfortable

When I first opened the mattress, it comes flat with the air squeezed out, it seemed way too soft. One day later it was perfect so don't be upset at first. Costco had this on sale which made it even a better deal.

My son loves his new mattress.

Mattress unfolded nicely, little initial odor. He slept on it right away and is quite happy to have upgraded.

Amazing bed

We bought our king and my daughter loved it so much she bought the queen and loves it!

Great quality

I had really good sleeps on this mattress.

Purchased September 2018. Delivered in about 1 week. Unpacked left open to air out Then put in bed . It’s great my son loves it !


Very good quality

Feeling comfortabl to sleep, Firm foam and sleep w

Bought this 2 weeks ago for my youngest son He loved it because he used to have a back pain of the old mattress, Firm foam made him fall asleep easily. Thanks God we got it

Good choice between, not to soft and not to hard

Provides firm support, especially at the edges, while supporting my back. This mattress is a good choice for "side sleepers"

Excellent Product !!

Bought this last year for my camper, and now I have them in my home. Very comfortable, Love it !

Great bed!

The mattress arrived in a box all rolled up and sealed. We rolled it out on the trailer bed board. It is not at full height right away but within a couple of hours it was perfect. I did buy a good mattress pad to protect it. It is firm, not hard though. We are both big people and I was worried about the past purchase we made of a foam mattress that we sunk into, making it hot and no support. All my worries about purchasing something sight and touch unseen were alleviated knowing we could return it. No risk here The first night we both slept very comfortably. No sinking in. No sore pressure points in the morning and not hot at all. This bed is as comfortable as our bed at home yay!!!

Super Comfortable

I have bought these mattresses on 4 separate occasions. Eveyone who sleeps on them loves them.

Super comfy!

I bought the bed three weeks ago and the mattress is very comfortable to sleep on!


Needing to replace mattress in newly purchased Motorhome and without being able to try it out first we were very pleased that 1.shipping time was as stated, 2.mattress is quite comfortable as well. Would do it again if need be.

We are very pleased

We are very pleased with this mattress. We purchased it for our family bunkhouse and it is working very well in that setting. We have recommended to our daughter already. Seems like a very good value for the money.

so far so good

Have only had mattress for a few weeks, seems to be comfortable, and nice for the price. was easy to open and after just a few minutes was ready for use. Time will tell how it will be long term.

Bought two

Bought two of them for my daughters about a month ago. Very happy with them. Great mattress for a great price.

Mattress a little firm but egg crate topper works

We bought this for our son. It is probably between medium and firm but there is no standardized rating system in the US. It is a nice mattress and an egg crate foam topper made the bed very comfortable for him. Even with the egg crate the mattress is a deal.

Comfortable, Supportive Mattress

We purchased a set of twin mattresses 2 weeks ago, and we're very satisfied with this comfortable, supportive mattress; it's firm without being hard and stays cool. We bought it specifically because it is not memory foam or innerspring.

Only sleep on a few times

This is in my rarely used guest bedroom and sleep on very little. The only two guest were my sisters and they both complained about the mattress. So, pretty unhappy and feel I wasted my money if my guest are not comfortable when sleeping.

Bought it just before

Bought it just before a 4 week RV trip. We've both slept really great the entire trip.

Perfect for the kids

I’ve had them for a couple months now and I was worried about the foam sinking but it works perfectly

Love it

We have had a few weeks to break it in and we love it! We got the medium king size and it is very, very firm. It took only minutes to reach the 10" and has not changed. Shipping was kind of a mess, the tracking kept saying it would be here and it took another two days, but still in the time frame alloted. No one picks up the old mattress which I thought costco totally would but a minor set back.

Awesome, comfort

Been sleeping on this for about 3 week. From day one I woke up with no pain in my shoulders,back,or hips. I'm 76years young and highly recommend this mattress. Arrived on time, no odor. Price was excellent. Love Cosco products!

Bought the mattress a month ago

Bought the mattress a month ago. Shipped to my house which was so nice. Love the pillow top but it is warm

Nice mattress

Bought this mattress a couple of months ago. So far happy with it. Easy to handle. Comfortable. The one negative is that the sides are soft so you have to be careful when getting off. Better to sit up first and not roll out of bed.

A year later

We've slept on this mattress for just over a year and are still very happy with it. It has yet to "canoe" our body shape into it (no "valley" or low spots) unlike past, more expensive mattress' have by now. We do rotate it as per instruction, every time we change the sheets.

Price was Amazing

Price was Amazing. 17 year old son likes it. Did not get the firm, got the softer mattress.

Over a month into using it and love it.

We bought this mattress for 2 purposes, to update my sons mattress and to have a comfortable surface for my mom to sleep on when she comes and will use his bedroom for her stay. My son loves it and my mom loves it. Me and my wife have a plush pillowtop hybrid expensive mattress and my done says his is softer. That's not the case. It does feel softer, but it's very supportive. Its surface pushes towards your back, neck and makes those worn throughout the days muscles feel cozy. The surface is supportive and hard enough for a 12 year old boy. Yet, it's at the same time comfortable and supportive. Unlike most memory foam mattresses, this one is not as firm.

Good option for guest room mattress replacement

Getting the box up the stairs was the hardest part :) It was easy to unbox and unfold, and I let it air out a few days without any problem. The odor was only slight and was completely gone before I put a mattress pad on. Our family said that the mattress was very comfortable (and they slept in while they were here so they apparently weren't telling tales). The suggestion to rotate it every two weeks for the first few months to allow it to "settle" makes sense - I guess I will rotate it between guests.

Best sleep ever

We bought this bed for my 92 year old mother. She loves this bed. We’re glad we bought it. The price was right for my moms budget and she says she is sleeping better than ever.

Comfort Tech 10 inch Twim XL mattress

Bought twin XL for my son (6’3” 193#) college apartment .. gets better nights sleep on foam mattress compared to his queen size comfort top Serta mattress at home.. no back pain re: history back pain from old baseball injury. Loves it so much wants to replace his home mattress with Comfort Tech!!!

Very Firm and Uncomfortable

I could only sleep on it 2 nights and my lower back hurt.

Purchased for a rental condo.

Appears to be as advertised. I have not actually slept on it.

I had a foam mattress

I had a foam mattress back in the '50s and enjoyed it very much for over 20 years. I recently decided to try another one. I found this one to be satisfactory for my needs. I noticed that some mentioned the smell so I was anticipating it. I didn't find any odor to speak of. The unit appeared to have been repackaged so perhaps someone had already aired it out for me. Anyway, so far it suits me just fine.

So much better than original RV mattress!

We bought this for our fifth wheel trailer and slept on it for 10 nights. Was very comfortable from day 1. Great price too. Was a little skeptical that there might be an odor based on reviews for many mattresses that I was considering. No odor at all with this one. Highly compressed upon arrival but grows to full size very quickly. Very pleased with the purchase!

Too soft

As soon as I got it out of the box I knew it was too soft for my mother. She suffered for two nights then we got help to return it to Costco. I don't think the kids would like it either. Easy return and I end up buying the spring mattress in the store. My mattress is a memory foam out-of-the box but definitely firmer with more support.

Replacement mattress for a Sleep Science mattress

Honestly, we have only slept on it 3 times so far. It's in a spare room. It doesn't seem too soft to me. My husband thinks it's too hard so we are not much help in that regard. This mattress was to replace a Sleep Science mattress we got through Costco. The Costco transaction for the Comfort Tech, as expected, was easy peasy!

One of the best mattresses!

I bought this bed for my daughter about s month ago. She fell in love with is after she sat on the same queen bed we have in our guest room. She absolutely loves her bed and tells us almost everyday what a great bed it is. Her old mattress was only 5 years old so, it’s not that she was sleeping on an old/outdated mattress. She just loves the comfort of Serene mattress. The price is great too!

Great Mattress

Love this mattress. Comfortable nights sleep

Waking up Feeling refreshed......!

We have had this for about 2 Months, and I used to wake up every morning with terrible back and body pain. I would have to take a steaming shower or Hot Tub and then stretch for 15-20 minutes every morning before I could do anything. Since the first night of sleeping on the Comfort Tech 10" Serene Medium foam mattress, I have wok up without any back or body aches...… I know it's hard to believe but it's true. I've been sleeping great and waking up feeling great ever since.

We love it, so comfortable

We bought this to replace a pillow top mattress and we have been so pleasantly surprised by how comfortable it is that we plan to buy another for our second home.

Guest room bed

We bought this bed for our guest room, everyone always raves about how comfortable the bed is! Very happy with our purchase.

Great mattress!!

I’m happy with the mattress and it meets my expectation.

Goldilocks approved!

This was a big purchase for my husband and I. I read many reviews before confidently pulling the trigger since it was Costco we were purchasing from. I am so very happy with the mattress. I was a little nervous because some people said the medium was too soft, some said the medium was too firm. I feel like it is just, just right! I would classify it as firm-medium. Very supportive, yet plush and conforming to the body. I was also curious about reviews that said if you sit on the side, the mattress gets weird. I disagree. I am a 160# woman, and when I sit on the side to put on shoes, no 'weird' effect. Thank you Costco for this nicely priced mattress. Great investment in comfort and rest, also I have scoliosis and this mattress is just great.

Great features

I bought 2 mattresses for my kids and they love it b

Easy to install

We love it. Bumped into each other with queen bed, so we purchased a king frame and this mattress. Haven't slept this well in a long time!

Ordered this a month ago

Ordered this a month ago. Arrived in about 5 days in large box compressed. We have slept on it about 20 days now. While we got the medium firmness, it is a lot stiffer than we thought. Not sure we would do this again. Frankly, trying to decide what to do with it.

Good price

It’s been 10 months since I purchased this mattress and it’s been several months that I started to feel achy in the morning. I realized it after being away on vacation and not feeling that way while I was out of town. This mattress may be good for young children not for teens or young adults

Sooooo great!!!

Searched through lots of reviews and best mattress lists. Finally decided on this mattress. My son loves it! Your body just melts in. Extremely comfortable, affordable, plus nice and thick. Make sure though you pick up a breathable waterproof mattress protector and you are good!!!

Very happy with my purchase

Very happy with my purchase. Great price and great product. I would definitely recommend anyone to buy. Very comfortable too.

Infinite comfort improvement

The mattress was easy to unpack and fit the frame perfectly. I am very pleased. It is so comfortable and no more backaches.

So far so good.

It is only a month old, but comfortable, easy to set p, and no smell.let’s see hoe comfortable it is a couple of years from now. That is the real test.

Great Mattress

I bought this mattress a couple of weeks ago and I got good responses from my family. They said that the mattress was very comfortable. I could a good deal. I would recommend this to my friends and family.

Great mattress for a kid-medium firmness

We are really liking this mattress. My daughter has had it for about a month now. It does feel like a medium cushioned mattress. I read all the reviews about how hard a firm mattress felt so I opted for this one since it is for a child and her weight is much less than the adults who claim the firm mattress is very hard. That being said, I have slept in her bed and have been very comfortable. The one down side is that if I’m sitting along the edge I tend to slide or sink off the side. Perhaps that has to do with the medium firmness of the mattress so there is give. It has not been a problem during the instance when I have slept in the bed. I have only noticed it while sitting reading in the bed when my weight is more concentrated. I give this bed 5 stars for a kid bed. I do think I would get a firm mattress if I were using it as a guest bed for heavier adults.

Too soft

Not happy with it. It sinks in... pretty much swallows you..

Best sleep I’m 19 years!

I bought this mattress for my son who is going to school in Montreal. After his first two nights sleeping on it, he said he slept the best he has ever slept and woke without neck pain which was unusual.

Worth paying a premium for this foam mattress!

Bought the full sized Serene medium foam mattress for a platform bed. It's exactly what we needed and with this, who needs a box spring?

just as described

I never had a foam mattress before. I ordered this and have no complaints. this mattress is not to hard or soft . would recommend this mattress. and the price was great also.

Best mix of soft and firm

I much prefer this to the super squishy feel of the softer tempurpedic. It has a nice amount of give but I don’t feel trapped like I do in other memory foams. I had no problems with the mattress expanding immediately.

Comfortable mattress

So far, so good! No complaints yet. Hopefully, I won't have any in the future. Very comfortable mattress.

Super Comfy!

I bought this a month ago for our family cabin. Everyone loves the mattress!!

Very soft

This mattress is not firm, its very soft

Best Mattress we ever owned

We decided to give this mattress a try after researching and reading the reviews. We had purchased top of the line mattresses only to find them after a few years uncomfortable and breaking down. We are so glad we did. It is the most comfortable mattress we have ever owned.

Good bed, great price

Ibought this for a vacation home. I know some people thought this bed was a little soft, but I thought it was on the firm side of medium... I don't weigh a lot. The best part is that it did not have that chemical memory foam odor! It says it needs to be rotated and I think I can do that - seems a little lighter than other memory foams and it comes in a zipped cover.

Love them!

We bought 2 of these and love them! Even my picky husband likes them! I did put a 2” memory foam pad on mine as I like a little softer mattress but I probably would have been fine without it. I really don’t notice much difference when on my husband’s mattress.

I bought this matress a month ago

I bought this matress a month ago and even as I have only had a few matresses in my life .. the ones that I did took dramatically longer for me to adjust to them .. this mattress became my dear friend immediately .. No time to adjust .. just fit right the first night.

Super comfortable and great value!

I brought this mattress

I brought this mattress for my mother, and she is happy and sleeping comfortably.

Great Bed

Very comfortable. Good quality. I’m not using a box spring, either.

So comfy! Great deal!

I bought the medium mattress, thankfully, after reading the reviews and comments. I would say it is on the firm side of medium depending on your weight. The skinny/thin people thought the mattress was firm while the overweight family members thought it was soft. I wanted a more cushy feel so I also bought a foam topper at Costco. I love it!

Bad odor

It has been 4 days and it still has a bad odor. Returning to Costco, which is extremely annoying due to such a large object. I don't understand why did Costco's quality check not do due diligence before offering this mattress for sale.

No tossing and turning

Happy so far! I used to toss and turn all night but now I sleep much deeper. Hip and lower back pain is dramatically better. Downside is that husband is sleeping so deep he's been snoring more consistently haha!

Comfy Bed, easy to set up

Very comfy bed, not too firm or soft. No strong smells, ready to sleep on the day of install.

As good as the one I paid 4x for!

Bought this for my RV, and I can't say enough good things about it. Finding an RV king is difficult to begin with, but was happy to see that Costco carried it for about the similar price as the lowest priced RV kings on Amazon. Figure Costco wouldn't put their satisfaction policy on just any product. The mattress is every bit as comfortable as a much more expensive mattress. Awesome it came in a box that was manageable to move around by myself. Been sleeping in the RV the past few nights simply because the bed is that good. Straight out of the package, there is very minimal foam smell. Standard sheets work well, since RV sizes are just slightly smaller than standard.

Extremely comfortable! Fit perfect in our camper!

This bed is extremely comfortable! It fit perfect for our camper. We truly haven’t slept this soundly in a long time. It conforms to your body without making you feel like you have sunk in. Great price! Highly recommend


I bought it for my 6 year old and he loves us. He says is super comfy and to be honest i am a little jealous! Is better than mine.

No complaints!

Fast delivery. Easy set up. Very comfy.

Fits the twin bed frame perfectly

We bought a trundle bed set and measured the top bed to 10” size mattress. Well it came and perfect fit and perfect look at ends and back. It was comfortable for a quick check and think it will be great for the grandchildren. Waiting for #2 8” to arrive but no worry as Costco never disappoints. Good buy!

Mini mountain

It’s comfortable and generally quite firm. The edges slant down towards the ground and the middle is super firm and higher than the edges. I’m not quite sure how that happens - maybe from how it’s packaged? My husband and I take turns sleeping on the middle with hopes of breaking it in a bit, but it’s been a month and no such luck. :/ We do love how firm and quiet it is but don’t know if we will keep it.

Queen size foam mattress

The mattress was firm, but honestly it was like sleeping on a concrete slab. It’s one thing to be firm. It’s another to be hard. Costco did a great job in arranging to pick it up and refunding our money. Apparently they only the firm mattresses in stock, or we would bought one from Costco.

Excellent musculoskeletal support for tall teen!

Teen daughter 5'10" LOVES this firm mattress. No more stiff back or painful shoulders upon waking.

Great buy!

Love this mattress. The difference in the new and the old was so tremendous.

firm mattress

very firm, but you can put a pad on if you like .

Good and firm

Firm mattress, very firm it took some getting used too but I really like it now

Great mattress with a value for money

Very happy with the purchase through Costco. Mattress has the right comfort and the firmness feels great. We have been using the mattress for the last 3 weeks and no complaints so far.

Not firm

It’s supposed to be firm. But it’s not firm at all.

Easy unwrapping and great comfort!

It took minutes to de-gas and was ready in under 30 mins. I would suggest to give it at least an hour or two to completely de-gas because it also tightens with it. When done, it is actually firm and like it much more than the Firm Zinus Mattress I had earlier.


Very good experience with this mattress.

Not firm

It says firm but it’s not firm. It’s sinks too.

Right amount of firmness

Comfortable and works with adjustable bed

I got the wrong mattress

I got the wrong mattress, I am beyond mad upset about it I ordered firm, and got a foam mattress, and it says that this item does not qualify for return

Best mattress ever.

The best mattress we’ve ever had. And a tremendous value to boot. My pins and needle and shoulder pin issue went away as soon as I switched from a Brentwood to this mattress.


I am happy with it so far

Good deal

Good product. Hassle free delivery

Costco Mattress

Good quality for the money and the firmness was just right

Perfect Fit

Simply Great! Great delivery, no issues with get back to form. Perfect fit to the needs.

Mattress in a box!

Great product. Wonderful price.

Good hybrid bed that provides firmness and cool

Bed is cool, came in a box and could be easily placed on the cot.

Average mattress

The foam mattress is average. Not sure how long it will last.

Great Mattress

Great Mattress and seems firm, the way I like. I'm a little concern about other reviews that said it gets soft over time.

Firm mattress

Looking for a firm mattress for our adjustable bed that helped with back pain . This has made a big difference. Be aware that mattresses for adjustable bed do not have a firm edge.


He really loves his mattress, says it’s not hard but just firm enough to be comfortable

Good mattress

Works as expected.

nice, but not firm

very nice mattress but not close to a firm one

Great at First

It was great for the first few months and now it has two divets from our bodies. This mattress is 6 months old! We rotated it regularly the first 3-4 months but the sags from our bodies in the mattress are huge and happened much too soon.

Extremely comfortable mattress for a great price!

Better than our $10,000 Tempurpedic Cloud Luxe which was WAY too soft. Excellent support. Very comfortable and the price is excellent

Good mattress

Good mattress, great value!

You have to buy this mattress

Fabulous mattress

value for money if it suits you.

It sounds weird that Costco is asking review for returned item anyways here is my experience. This was our first memory foam so we didn't know how it worked out. I always wanted to try out memory foam. We bought the firm one as we knew only firm will work for us. As it turned out I was fine with it, it's kind of neautral for me. However wifey was not waking up with pain in back and neck area. We tried for 3 weeks and than gave up. We bought from Costco for the reason of easy delivery and easy returns. and Costco stands by it. For Mattress there is no one size fits all, you have to try yourself and then only you can decide. I think its good value for money mattress.

No more back aches.

Love our new mattress. No more achy back in the morning. Ready to go after 7-8 hours of expansion time.

You won't regret it!

This is our 1st ever all foam mattress. Firm is just right with just a hint of give. My wife & I total just below 400lbs. and it doesn't dip when we sleep close together. We let the mattress set for 12 hours before sleeping on it. It wasn't advised or anything, we just figured it wouldn't hurt anything. Best purchase of 2020!

Lives up to its billing!

Much better mattress than one costing 4 X the price of the Serene. I would suggest airing it out for a few days after unpacking.

Excellent mattress

Very firm but comfortable mattress! Honestly i have slept better in this mattress than with my last $2,000 Tempurpedic mattress!

Love it

I love it, very comfortable

Good value and comfort on some levels

Still in the phase of I’m hoping it’s good mattress. Some chronic body pain feels better due to the mattress being firm and molding to some body areas. But not comfortable for me on sleeping on side. Definitely hard on the body but it could be just me. Delivery was fast, no odors, easy to put in bed frame. Great price but the jury is still out. : )

Looks good

Very firm even for a 200lb person but its in the guest room.

awesome bed

Thus bed is worth the money. It is so comfortable and I have been getting some of the best sleep I have had in a while. Good if you like your beds squishy


If you want to feel like your sleeping in a chemical factory certainly purchase a Comfort Tech Mattress made in Canada as per the documentation supplied with this product, I have had this product for 1 month my place stinks like chemicals, cant sleep, you name it. Bought new quilt and bedding, this all needs out be thrown out. I cannot believe they are allowed to sell this, is it not CSA approved, that is the next company I will be contacting

Firm, Hot and Stinky

Firm was very firm and felt very conforming when laying down. It was not comfortable. It was very hot and smelled bad. We returned it.

Not firm whatsoever

I bought these based on reviews saying that the mattress is firm. The foam is very soft. When sitting on the edge, it squished in to about 2-3 inches. When lying down it feels like a plush. This shouldn’t be advertised as a firm foam mattress.

Two stars because it took 4 years to implode

Well, maybe not implode, though after only four years one of the sides caved and is causing hubby to roll off the edge. Not good when it decided to do this after major surgery. We bought it through Costco in 2020. Previously bought a memory foam at Costco, which after ten years, I foolishly decided we needed a new one. It was a great mattress. (Costco stopped carrying it which is why we got Comfort Tech.) No more Comfort Tech for us.
