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.View More Reviews
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.
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.
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.
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.
I was skeptical because of the price but we loved it from the first night! More comfortable than our Temper-Pedic
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 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.
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.
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...
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 foam...it 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!
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.
Very comfortable. Great price
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.
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!
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.
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.
Very happy with the mattress, process and delivery.
I bought this abut a month ago for my son, he loves it!
I love this mattress. It's firm but not hard or uncomfortable.
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. So far he is happy with it. He said it keeps him cool around his body. So, he sleeps well.
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.
Mattress unfolded nicely, little initial odor. He slept on it right away and is quite happy to have upgraded.
We bought our king and my daughter loved it so much she bought the queen and loves it!
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
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
Provides firm support, especially at the edges, while supporting my back. This mattress is a good choice for "side sleepers"
Bought this last year for my camper, and now I have them in my home. Very comfortable, Love it !
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!!!
I have bought these mattresses on 4 separate occasions. Eveyone who sleeps on them loves them.
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 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.
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 of them for my daughters about a month ago. Very happy with them. Great mattress for a great price.
This bed was perfect and everything I'd hoped it would be... at first. After having if for a few months it seems like it's wore down in the middle of the bed where I tend to lay more often. If I try to lay on the edges I just roll to the center. It seemed to good to be true at first, but I don't think they're built to last.View More Reviews
I feel like it already may be sagging in the middle since that is where I sleep the most, but is very soft and comfortable
I waited a long time to write this review because most beds are great when you first get them. But there are huge sleep indents where my wife and I sleep, and one big raised lump in the middle of us. I'm a big guy over 250 pounds, but my wife is barely over 100 pounds. I understand how my side has been messed up, but not hers! Now after 18 months of sleeping on the mattress it is way too soft and way too lumpy and we are searching for a better brand.
I wanted a memory foam mattress for years after sleeping on one on a hotel. I refuse to pay $3000 for a mattress. I bought this after reading the reviews. I have had the best several months sleep ever. I don't wake up sore anymore. We did not experience any of the smell reported in other reviews. You absolutely cannot beat the price!
The mattress arrived timely. We let it rest a couple of days before using it on the bed. There was little to no off-gassing smell and my niece says it sleeps very comfortably. Very good purchase! Thank you.
When I see this in the Amazon Primeday, I said to my self 'I Want One Of Those'. I have full size bed frame that needs a bed mattress. As advertised, a full size is measured 75 x 54 x 10. I like as it is 10 inch thick. Ordered a full size, got it. packaged like a vacuum seal, it is heavy . Opened and placed it on my bed frame. And now I said to my self, Oh! NO!! S....!!!. It is wider than it is advertised. It is 56 inch wide, and it won't fit my bed frame. Mattress is firm and has a nice cover. I will return it and now my problem is re-packing it back to its box. Maybe return it in several pieces. Very dissappointed
This mattress was a steal!! I was so skeptical due to the low price but I am SO happy I ordered it anyway! It's firm, yet soft. Excellent quality. I've never slept so well. The only downside is being so comfortable that it's difficult getting out of bed in the morning!
so easy to set up. SUPER comfortable. My husband who is in chronic pain from just being a dum-dum when he was young sleeps better on this than any bed we have ever slept on.
Wow, I love this mattress. Just a fair warning, I never owned a memory foam mattress before this 1 so maybe I'm just too biased towards it. It's firm enough to support me sleeping on my back and soft enough for me to sleep on my side with no issues. It supports edge sleeping very well not that I like to sleep on the edge since I tend to fall off my bed when I do lol. The only thing I really really really disliked was the VERY strong smell coming from the mattress when you first unwrap it. Highly recommended you let the mattress air out for about 2 days. After I've done that I haven't smelled anything coming from the mattress.
I used to have insomnia. USED to.
The mattress is great I would say up their with the serta i comfort line and without the high price.
The mattress has great support for the body and even has edge support and does not heat up like other memory foam mattress.
I am not really a one position sleeper and have no complainants unless you want a extra firm or a ultra plush mattress as I would rate it the sweet spot.
I love this bed. I was a bit skeptical initially as I have never purchased a bed without actually going to the store, however I did a little research on the company and made the purchase. I am very happy with it. I look forward to purchasing another one when I have a place to put it.
It was hilarious seeing a queen size mattress come out of that (relatively) tiny box. It had hardly any 'memory foam' smell out of the bag, even less after letting it sit for 24 hours. Very comfortable, but one of the firmest mattresses I've ever slept on. If you don't like a very firm mattress this might not be the mattress for you.
Good mattress for the price. Hard to tell if it will hold up over time. Edges a bit soft.
I received what appeared to be used mattress with oil on one side and tears on the other.
We have had the mattress about 3 weeks and it has exceeded my expectations. My old mattress was very expensive and it was never this comfy. I always woke up extremely hot and sweaty,so you know my concerns about switching to memory foam. I'm soooo pleased ,cool and rested. LOVE IT!
This bed is firm. If you like a firm mattress, you'll probably love this one. Personally, I expected more shape contouring from a bed this expensive. To find out why it's not great I unzipped the top cover to discover it is simply an 8-inch piece of upholstery foam with a 2-inch piece of memory foam glued on top. That's it.
On the plus side, the cover is stretchy and seems like relatively good quality except for the fact that it has a part where it wasn't sewn correctly and is falling apart along 2 inches or so of the seam. My wife likes (but doesn't love the bed). I am sleeping OK, but find it uncomfortably firm. I've gone ahead and put another 2 inches of memory foam on top of the bed and I'm hoping it will soften things up to my satisfaction.
Another positive feature is that there was very little odor when we opened the package and it dissapated quickly.
