We bought this for my daughter (10), and she LOVES it! I was a little nervous about it, but after several reviews assured me it was comfortable, we purchased it. I wish I had bought it sooner! It has been great! She sleeps better than ever! Like others, we let it take shape for about 36 hours before putting it in her room.

We bought this mattress for our 3 year old and so far it has been great! It expanded as stated and it did have a slight smell but that was gone within a day or so. My husband has slept on it and said his sore back feels great in the morning. We are pleased.

I purchased a foam mattress years ago and needed another one. So I went on line at Sam’s club.com and purchased this one. It arrived just as promised. After taking it out of the box as instructed and placing it on the bed to allow the mattress to fully form its correct shape, what an amazing comforting product!! Even days after it had continued to form and firm!! Extremely comfortable but firm!!!

Bought this a CPL of weeks ago for our toddler to transition into, and to double as spare room. Family is in town now and said it's very comfortable. Also, I was worried it may take time to flatten out from being shipped rolled up, but it flattened out right away. Very Happy with this bed!

Jeepers this mattress even helped my hyper dog get some deep sleep with soft snoring!! She didn't even get up when I made a restroom visit. I'd say the pressure, weight and pain I've felt between my shoulder blades for over 20 years has lessoned by about 70%!! It could be that what is left is residual from my back bothering me for so many years. I wish I had bought this years ago if it was available and what an excellent price!!

Seemingly contradictory, I wanted a mattress that was really great to sleep on, but I just didn't want to pay a lot, so I 'took a chance' on this one, and got lucky. It's sleeps great. I could have easily paid more, but I can't imagine I would have been more satisfied.

Bought for my son to replace his twin size mattress. Paired it with a metal frame the mattress sits on. The mattress took about 3 hours to reach full size and did have a strong smell initially, which makes sense since it was manufactured and sealed right away. We set it in my son's room and opened his windows for a couple of days to "air it out". After a couple of days, there was no longer any smell. Even after 1-2 days, there was barely any smell, but we wanted to be sure since other's had complained it never went away. Maybe they should have aired it out for longer? We bought a mattress protector and my son has said it is super comfortable. My wife and I tried it out and it is more comfortable than our more expensive mattress. If you need a guest room mattress or a replacement that is not expense, we think this is a great option!

I live in a remote location and this was the perfect choice for a reasonably priced mattress. It is a little softer than I would like but the firm mattresses I have tried were rock hard so I'm pleased with the choice. It does have a very slight smell of the rubber that it's made of but not offensive as some reviews suggest.

Everyone who has slept on this bed thinks it’s very comfortable. It was easy to unpack and fully inflated within an hour. It had a bit of a toxic chemical smell so I left it to air out with the windows open. It didn’t take a day before the smell was completely gone.

Very disappointed that it never rose to 10" level-- stopped at 8.25". Only reason for a couple of stars is because Sam's Club accepted the return with no problem. The mattress construction looked same as the one I have, which inflated instantly to the full thickness upon opening the box, but Zinus mattress never reached the height after 5 days and nights. Should have listened to the other reviewers with the same issue.
