I am aware that these mattresses will have an odor when opening, that was expected. We are now about a month out from it being opened and I can still smell it when I walk into that room. I am seriously considering returning it regardless of the fact that it is comfortable. The smell is just overwhelming for me.

Bought for my husband to use while he repairs our house. He's a big guy over 6'4" and 250lbs. He said he sinks a bit into it, just being so large, but it really is holding up well. The mattress is comfortable, not too firm. He did end up putting a boxspring under it.

Medium firm purchased, its way to soft, zero support. I am so disappointed, my 10 year old mattress was way better. I threw away the packaging so return is out of the question and even if I had it how do you roll it back into the box? Mission impossible.

Better than expected. I did NOT like memory form mattress because I prefer firmer mattress with steadily support. I hate the endless sinking feeling that my husband's old memory form had as well as others I have tried. But this memory form mattress from Sam's does not give me that sinking, unstable, wobble feeling when in bed. I choose firm and to me it's medium. But good enough. I think firm is ideal for face-up sleepers but less ideal for side sleepers. The remaining question is how long can it stay in shape without becoming too soft or even collapsing.

Our guest reported that this mattress was very comfortable. For the price (about $300 for full-size) it appears to be an excellent value and I was able to pick it up and transport it by myself (comes in a rectangular box). Just needed help getting it upstairs.

A little larger than 60"x80" standard queen, overhangs the box springs about 3" on each side, not really an issue, just observation. Replace a foam "Sealy" mattress, this unit is much warmer than the Sealy, the upper memory foam is softer, and the underlying foam does support well, for a "medium" firmness. Had to modify covers to compensate for additional warmth of the mattress. Sturdy mattress, somewhat heaver than previous, hope this means more foam.

This was easy to open and The box is heavy FYI, if you are bringing it upstairs. It is a medium firmness, i think it is more soft to medium. I've slept on it for two weeks and it is comfortable, and it kind of conforms to your body. I am happy. I wanted a little more firmness, but it is fine.

Absolutely love! It arrived in an easy to handle box (little heavy but manageable). Packaging was great but you need to have your mattress where you want it before you start unpacking. As soon as you start unwrapping your mattress is going to continue to increase in size. It’s so comfortable and it has the cooling fabric. Highly recommend! We are now replacing all our mattress with this type.

Our daughter graduated from college and moved out so we gave her all the furniture in her room. We were going to buy an air mattress for temporary use for guests but decided to get this mattress for them during the holidays. Everyone who slept on it commented on how comfortable it is. Definitely a good purchase and can now become permanent for guests visiting over the next few years.

I purchased 2 Twin XL 12" medium mattresses to use with a King platform bed. While the mattresses expanded quickly, had no smell, and a perfect medium feel (not too soft/not too firm), they are not anywhere close to a Twin XL dimensions (38" x 80"). Within 15 minutes of unboxing, they each expanded to nearly 42" wide. Height only got to about 11" as well. 84" wide will not work on a 76 1/2" wide bed. I ordered online so they will be picked up, but it was a complete pain to have to plastic them up again for pick up.
