Bought our daughter this mattress (size queen) and the Serta queen foundation. The mattress is only 10”, not 12”. The foundation is 1.5-2” more narrow than the mattress, and it is also shorter than the mattress. Very disappointed since the smaller foundation means less support on the edges and there is a gap the whole around it and the bed frame

I like a firmer mattress, but this was ridiculous. We bought this for a second bedroom and our family who first slept on it woke up with back pain. I later tried it and could not sleep more than an hour before my discomfort woke me. Avoid u less you like really really firm beds.

I have chronic back pain. Surgery did not help. I, in fact, may have made my back worse. This mattress is too firm for me. After two hours, I need to get out of bed because the pain is unbearable. Keep in mind, it is not the mattress but I could not recommend it based on my experience.

This gel/memory foam mattress is like sleeping on a 2x4. It has, at the most, 1/2 inch give to it. It is so uncomfortable. This will be going back as soon as we order another one. We have had memory foam mattresses in the past, and they were plush and supported your joints. This one is just way too firm. If firm is what you are looking for... this is the one for you...

We have tried this out for a few weeks now. I know it just my opinion, but I was so hoping this would make a difference for me. I’m about 5ft 120 lbs and had a car wreck years ago. I have neck issues and was hoping this would allow me to get a little more sleep. I know it’s not going to fix me, but I need sleep. My neck and shoulders have hurt worse. It’s very firm. It may be my mistake completely, but I really thought this was one of those mattresses that when she lying and it kind of phones in my woods around you. If that’s what you’re looking for this is definitely not the one. Not saying this is not a good mattress for somebody, but I definitely need to do some more research before I go out and shop again. Returning this today.

We love our new mattress...unlike other memory foams that ship in a box, we slept on it the first night. It is definitely very firm. I would prefer not so firm but my husband likes it and says it has helped his back. I find it easy to fall asleep on this mattress and it seems pretty cool with the gel. Great price too!

Bought the Serta 12” Luxury Gel Foam mattress (Queen size) a few weeks ago at Sam’s marvelous $100 discount, and liked it so well that I bought a second one right away for my guest bedroom! Consumer Reports rated this mattress as their #2 Best Buy (Mar 2018) at full price, after exhaustive testing, ahead of much pricier competitors. Comes in a box, easy to unfold once you break the vacuum seal... use a scissors to cut the plastic to avoid accidentally slitting the mattress. No foam odor. Expanded depth is more like 11”. Judge it to be medium firm. After much research, I feel this is the most reasonable, comfortable, portable bed solution!

If no stars were an option, that is what we would give. Me and my partner are both heavy sleepers that have never had any problems sleeping anywhere. That being said, we are now on our 3rd sleepless night. This mattress is like a rock with no give whatsoever. We decided after the 1st night to give it a few more nights to see if we might adapt to it... At this point I don't think it's possible. We had our last mattress for 15 years and it was completely worn out...that one was 5 stars compared to this one. I would strongly suggest looking elsewhere for a mattress.

We bought this mattress 5 months ago. For the 1st 2 weeks, we could not sleep due to the gas odor. We thought by airing it out, it would go away. It is still extremely bad after all this time. The odor gives us headaches and congestion every night. It is too expensive to throw away, but I am concerned it is dangerous to sleep on. I would not recommend this mattress to anyone. Sam’s certainly should not be selling this mattress.

I inherited the original tempurpedic foam mattresses and loved it. I recently moved and left it behind (EXTREMELY HEAVY). I needed a new bed that wouldn’t break the bank! I purchased this mattress in a box and am so glad I did! I had done research and couldn’t afford the thousands for a comparible type bed and finally decided on this one. I am so glad I did! I will look for this type hands down for any other mattress purchase!
