So far I like it. It is more firm than I normally would like, but yet it was still very comfortable. I slept very soundly. Only time will tell if this continues. As far as the height of the mattress, after leaving it unfolded in my living room for 24 hours, then moving it to the bed(the move actually added more height), it now measures 12". See attached pic.

Purchased this bed and the mattress corner edges never expanded to full size, Sams told me in order to return the bed has to be in the box, but if it was a regular mattress I could easily return it without even bringing the mattress back mind blowing experience. Even though on the box Serta says it’s can be returned

better than i expected.

Bought it in club. It will only expand to 10 inches, not 12 inches. If I wanted 10 inches, I would have paid less money for the 10 inch mattress. SERTA won't help if you don't buy it off their website, they send you back to talk to SamsClub. Club says you have to wrap it in plastic shrink wrap and find a way to drive it back to the Club. So if you don't own a Truck, then there's no way a Queen size mattress is going to fit in your car to return it. There is no way to shrink it back up. Ugh... All you get from samsclub is SORRY.

This product is a memory foam & latex foam mattress. I don't believe it's a hybrid. I don't think there are coils in it. It comes delivered in something like a 2x2x4 cardboard box. The mattress is vacuum packed in plastic, folded in half, and rolled up. Once you cut it open, you have to let it expand for a few hours, even a day would be good. I would recommend that you don't throw away your old mattress just yet! After opening the new one, let it sit in the garage for 2 weeks prior to using, as the outgassing fumes are terrible and most likely not good for your health. After replacing the old mattress with it, you should run an activated charcoal air filter in the room for a couple months to take out the remaining VOC's that outgas.

Came with big stains

I brought this bed 6 days ago despite the not so good reviews. Finally slept on it lastnight. The worst sleep ever me and my husband tossed and turned all night. My back and neck are killing me. By the way i have no back or neck issues. The bed was hot, extra extra firm, had no give, and stiff. I literally felt like I was sleeping on top of wood planks.

Had the bed for over a month and agree with the person that said it was fine for heavier people. I'm not sure if the guy that said he was 240 lbs was reviewing the correct mattress, but I'm closer to 300 lbs and there is very limited sinking and turning over is not a problem. Consumer Reports rates this mattress very high even among spring/foam fusions and the more expensive $1000-2000 beds. They even rate it a 7 out of 10 in firmness, which I agree with. If you are looking for something similar to laying on concrete, then maybe this isn't for you, but if you want something with mid-high firmness, you'll be more than happy with it.

We bought this in the summer after reading so many great reviews. It's such a hard mattress. And even after adding a $200 mattress topper, my husband and I wake up so sore. Not sure if I should contact Serta or Sam's Club for any kind of option.

This is the first review I've ever left but I think it's important and hopefully it will prevent someone else from having problems. I bought this mattress due to back issues. It started out great-for a few weeks. Within the first month it got a very large dip where I sleep that is so bad you can see it when the bed is made. After two months I rotated the mattress and now there is a dip in the new spot. For reference, I weigh 120 pounds. My back is worse than before I got the new mattress. I have only had this mattress for a few months. I have much less expensive memory foam mattresses that I purchased for my children from another company that have held their shape for over 5 years and are clearly higher quality products. This mattress is terrible. I regret ever buying it.
