I purchased this mattress because a family member also purchased it and loved it. I have colorectal cancer and sleeping became difficult with the radiation and chemotherapy protocols used to treat my cancer. This mattress has been amazing in the comfort, support and coolness. I've seen more expensive mattress, but not better. This mattress has been much more than advertised. I'm very glad I purchased it.

It’s a good mattress. It is not as firm as I imagined it would be, but it’s far from terrible. I have chronic back issues and have found that firm mattresses are the most pain-relieving for me. This one does have some “give” but not too much. It’s not rock-solid like some other firm mattresses.

Bought this for our son's room/guest room. The bed had an older mattress and he has lived away at college since 2014. After graduating college in May he was home for the summer and realized how bad the old mattress was. We bought this and put on the bed for his Christmas visit. He loved it.

18 years ago we bought a similar mattress from Sam's Club and were extremely satisfied with. it. This one we have not liked as well. 1. It took longer to fluff out, so we had several nights of sleeping on "wierdness" while we waited on this to happen. However, it did fluff out as predicted. 2. It is extremely firm. Much more so than our last mattress. I liked it, but it hurt my wife's back. Se solved this by buying a mattress topper. I feel that it is a good quality mattress if you like firmness. Now that we have the topper, it is great.

Not actually 12”, barely 11”... love the mattress but not truly 12”... based on other reviews seems like this is a common complaint.. did i mention that i sent it back and was sent a replacement the same width...11”!! honestly i love the mattress but wish they would have advertised it at true dementions.

We bought this bed about a month ago, we didn't want to spend 1500 dollars again on a mattress set,since you can't flip most mattresses any more! The more exspensive need was definitely more comfortable , but for a third of the price, this one will work, for now ! Getting it shipped in a box was definitely awesome though!

Best sleep I have had in years. Have had it a month. After a week it hurt my husband hip (he is a larger guy and prefers a soft bed) so we got a 3" cooling memory gel topper and its been great. You wont be sorry getting this. If it's a tad too firm just buy an egg crate topper or gel topper

In store, presale ,the mattress was in a wheeled box with a handle for easy handling. I ordered on line and it was to be delivered i 3 weeks. the next week it was delivered in a non wheeled box. I flipped the box end to end like a workout video of a body builder flipping tractor tires up a stairs to my bedroom. No instructions on or in the box of how to unpack it, care for it or the warranty. We pulled it out of the box and carefully cut the plastic bag and it inflated... fully after 4 hours. No care instructions in the box. Sams referred me to Serta. Serta said Sams has the instructions. Sams sent me back to Serta. Serta said Elite Comfort Solutions ( the subcontractor that makes and ships the mattress) may be able to email me care instructions and warranty. No response from them. The mattress is firm and after a week developed swales on each side we sleep on.

Very nice. Takes getting used to, compared to an innerspring mattress. No bounce at all. My back hurt some after the first 2 nights, but once my body adjusted, no problems. It is a little more firm than my personal preference. I am a big guy and I was worried about being hot. So far, it is very comfortable.

I replaced a old spring mattress with this Memory foam one. I have been watching the development of the foam mattress for a while. I was always worried about the heat and the mattress being too soft. This mattress has multiple layers to keep it cool and is firm. I have found that I do not wake up in the night or toss and turn as much. It gives great support for your back while contouring to your body on your side. I would definitely recommend this mattress.
