Bought this for the reviews, it is NOT FIRM at all. Actually going to return it. Not sure on the great reviews. If you want soft and squishy and back breaking go for it. NOT FIRM, returning it due to so soft I am crippled. I ordered firm for a reason and this is not it.

The reviews about it being too soft are correct. I have another memory foam mattress. Different brand. That is plush and isn't nearly as soft as this medium. It feels like you went to sleep on an air mattress and woke up in the middle of the night and it was flat. This is excessive. I like plush. But this is next level. It almost has me wondering if they put the wrong one in the box

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.

The bed came well packaged and very securely wrapped. As soon as I opened the packaging it completely sprung into shape with no issue. We're waiting a full 24 hours before laying on it. We ordered the medium and it's plenty soft and plush. I think it's perfect for my daughter but for me personally I would use the firm.

I have purchased 4 of these over the last 2- 3 years and will continue to purchase them. I had my doubts based on the price point, but I was pleasantly surprised. I originally bought them for me kids and they liked them. I recently purchased one for my guest room and have slept on it the last 2 nights. I realize that I need to replace my own mattress after only 4 years because I slept so well on this one!

this mattress is terrible. only expands to 10 inches. when you sit or lay on it, it goes down to 2 inches. then when you want to return, they'll send a fedx truck to get it, but then , you are with out a bed. so to try and fix the problem, i brought a 4 inch pillow top. more money down the tube. in short, its junk

Defective-as others have stated, it has a lump in the middle. Bought it for my guest room. Contacted Sam's through chat to find how to complete a return. They just said I needed to talk to the store. Store said I could put it back in the box (which is impossible) or wrap it in plastic. Then I get to stuff it into my car (which it won't fit in) and drive it back. I also don't live near Sam's so this whole thing is incredibly inconvenient. I tried to upload a picture, but this app only gives me an error message.

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.

Delivery from different locations took longer than initially projected. One box was overstuffed, as if it had been repackaged. After a few days they mattress was about 10.5 tall and 4 inches too wide at 42". They have been slept on 2 weeks and unpacked about a month. Still over 40" wide, making the 2 5-6 inches wider than a split king should be. Its risen a bot to almost 11", but still an inch short of 12" expected. It is plenty plush and not uncomfortable to sleep on but sheets and mattress pads were strained fitting over and likely why they measure narrower now. Not sure they'd stay compressed width wise with both off.

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.
