We tried this mattress but had to return it after the second night. It was like sleeping on the floor. Sam's Club gave us no problems with the return.

I have had this mattress just over a year. A couple months ago it started sink in the middle, causing you fall towards the middle of you sleep on one side. This makes it very difficult to sleep.

We bought a 12 inch serta sleep to go mattress and it only measures 10 and a half inches we have been told nothing can be done about this.. Garbage product don't buy...!!

I weigh about 450lbs. I usually wake up every 1 1/2-2 hours in my old mattress. Since day one I've slept through the night peacefully waking up only once a night.

I bought this mattress 3 months ago and it's already sagging and soften. My back hurt so bad, I couldn't get up in the morning. I has 10 year warranty but only after 3 months it's sagging and deformed. Don't buy it or you'll be sorry.

I was skeptical about this mattress but it is very comfortable. I bought it for a second home so haven’t slept on it more than a weekend but so far so good

I bough a queen and a King they are both as hard as a rock, I was expecting something a lot better form Serta and It’s 10” not 12” they both are going back to Sam’s club. What a waist of time having to bring them back to Sam’s.

Not as firm as I expected. We bought the exact same mattress model, in a queen size several years ago. The mattress we received recently is not as firm, we sink to the frame when we sit on the edge.

Very comfortable, does get hot/would recommend a serta cool mattress cover. Down side, mattress only expanded to 10” instead of 12” even after a wk & 1/2.

The mattress is comfortable and does not have the chemical smell some alluded to. It is not a 12” mattress as advertised. I have had it for almost a week and it is 10.75 inches.
