I've had this mattress for a little over a month. At first, I thought it was causing me to overheat, as I would wake up sweating almost nightly. However, I eventually thought to remove the waterproof cover that I was using to keep the mattress in good shape, and as soon as I did, any heat issues were resolved. This mattress sleeps very comfortably! It's a great height, looks very nice, and had no smell upon arrival. I was able to carry the box inside myself, and it inflated rather quickly. For the price, this mattress seems like a steal!

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.

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 for our daughter as she was sleeping on a very old spring mattress. Her friend recommended a memory foam mattress. After some research, we decided on the Zinus Night Therapy. She loves it, much more comfortable than a spring mattress!!

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!!

We have three of these mattresses. An 8” and 10” twin size on a bunk bed.”, and now the 10” queen for my daughter at college. She is so happy with it. The other two still love theirs after having them for years. Everyone sleeps great on them, which is the most important thing.

It's a nice foam mattress for the price....... it's on a bed in our extra bedroom. You do sink down into the top, then when you go to roll over, you can feel where your body has made "indentions" in the foam. The foam mattress on our master bedroom bed does not do that...... maybe the foam is firmer??? This mattress is ok comfortable though, and I do not wake up sore.

Purchased for my 22 yr old daughters’ bed. She loves it. The old mattress had begun to cause back stiffness and pain, she would complain every morning that she was not sleeping well. Now she says she sleeps soundly without tossing and turning and no more stiffness and back pain.

We purchased 3 of these mattresses (queen). Two were for bunkbeds and one for a murphy bed. The level of softness does seem to vary to some degree, but overall I think it is very comfortable. My youngest daughter is 10 and cannot easily weigh down a sack of potatoes, so for her it is a bit firm. I would consider this mattress medium firm and good for the average person or child 13 years or older. There was no odor, and the mattress came to about 9.5" by the end of 5 days. There are some indents in the middle foam at the corners, but it doesn't seem to compromise the structural integrity at the corners (but worth removing one star as it's not perfect). Sam's shipping was quick and reliable.

I bought this matress for my daughter. I shopped around and this particular one had great reviews and was an unbelievable deal. My daughter has had it for a month and really likes it. I will definitely purchase another one for myself - ordering and shipping all went smoothly!
