There shouldnt be any bad reviews for this mattress..it does just what its supposed to Right out of the box instantly more than 12 inches on every side...and soft yet firm just right My daughter and I love it...perfect mattress at a good price

Very nice and very comfortable mattress we got this for our kids going to college and he's sleeping really well on it I would recommend people buying it

We purchased this mattress for my mother-in-law. So far, she is very pleased with it. She says it is extremely comfortable and she's able to sleep well on it.

Ok for the price if you don’t care if it’s truly a 12” mattress. Had it open for 5 days and never inflated to the 12”. Was about 10-1/2”. Smell didn’t dissipate either. Returned this item.

I have purchased one in the past. This one did not fully expand in one corner. After 48 hours. And measuring its barely 10 inches. But comfortable. Price should be reduced.

Item came in damaged. It also didn't fully expand, perhaps due to the damage. Return and refund process is also a nightmare, and Sam's expects you to take some of that burden of the process.

This bed is very comfortable. I wish the outside edges were more structured because it’s very soft/squishy when you sit on the edge of the bed. Also it smells super bad and after 10 days the smell hasn’t dissipated.

This is a very nice mattress. At first I felt it was a bit too firm, and I prefer a softer mattress that still is supportive. It did take a couple weeks of sleeping on it to start feeling a bit softer and is now the right mix of soft and supportive.

Nice mattress. Bought for my son and his initial reaction was “Will it flatten out?” And then “it’s too soft” but it turned out perfect. He’s very happy.

I've had this mattress about two months now, and it never really settled like it was supposed to. Didn't reach the height it was described as and very lumpy in places. Very disappointing.
