I was a bit spectical at first about buying a Sam's Club (Member's Mark) branded mattress at such a low price. I've always had a Sealy, Serta or a Sterns & Foster. I figured that it wouldn't be any good. But I read the reviews and decided to give it a try and boy am I glad I did! This mattress is AWESOME!!! I've had two spinal disc surgeries about 4 years ago and finding a comfortable mattress, with the right support, has been a challenge to say the least. I've been sleeping on a $2,000 Sterns & Foster for the past 4 years that was supposed to be "top of the line" in comfort, but even that mattress doesn't come anywhere close the true comfort of this one. I purchased the Queen size at about 10 in the morning and even though on the Sam's Club website it recommends that you allow the mattress a full 48 hours to conform to it's full size, mine was fully conformed in a matter of a few hours. I was able to sleep on it that same night. It was the first fully restful night's sleep I've gotten since my surgeries. It's nice and plush, but not so soft that you sink into the middle of it. It's got just the right amount of firmness for that much needed support. I've always been a hot sleeper and I found this mattress keeps me at a cool level of comfort all night long. I don't think I can say anything else about it other than it's just a really good mattress, and for the price, you just can't beat it!

Bought less than a year ago and is complete garbage. The matress already is sagging in the middle and if you lay to close to the edge you will roll right off because there is no structure to the edges of the mattress. Don't waste your money and can't return it because the store policy only covers the first 30 days. I would give it zero stars if I could.

The manufacturing chemical smell has not gone away after letting this mattress air out with the windows open and no cover on it for 48 hours. With a waterproof cover, mattress pad, sheets and comforter, the room still smells and my hair even smells like the chemicals after sleeping in it. It's a decent mattress otherwise although you will slide off if you try to sit on the edge of it. It's very soft.

I was very disappointed. This bed was warm and worse way too soft. It was so soft the sheets were constantly popping off. After calling Members Mark and trying it for almost two months this bed had to go back to the store. Check out the new Casper line… Im MUCH happier.

I had such high hopes for this mattress as I am a big time lover of the Members Mark brand.. however, this mattress did not prove its 4.5 star review. I tried to give it the benefit of the doubt despite seeing reviews about the mattress only inflating to 10 inches but that has proven true in my case as well. The edges of the mattress remained compressed and the cover fabric was loose due to the lack of foam inflation. Sadly I will be returning this mattress.

I bought the medium firmness in store and it feels like plush. Too soft. Perhaps if I had bought the firm, which they don't have in store, it'd have worked. But they won't ship to CA. What a shame, I really wanted to like it. On the plus side, it did not smell bad. And the quality seems to be very decent for the price.

Buyers beware! This mattress is comfortable in the center, however mine never formed on the sides. We waited 52 hours to get on it but it never took. Since then I've been trying to get a refund or a replacement on it but sam's refuses to take care of it. They keep saying they need to pick it up before they will issue me a refund but THEY WON'T PICK IT UP. I keep calling over and over and over again to get it scheduled but they keep telling me i have to wait to be contacted. Sam's club online customer service is by far THE WORST customer service i have ever dealt with. For everyday purchases, Sams is great. But if you're looking to make a large purchase with a "warranty" i strongly suggest you buy elsewhere. Sams does not stand behind their product and they make it outrageously difficult to get help.

It starts with the unpacking. You will have to unwind layer upon layer upon layer of plastic - just great for the environment. First time I sat at the edge of the mattress I completely sank into it and my legs disappeared in the foam - I am only weighing 170 lb, mind you! Then I tried sitting at the top of the mattress, a large foam cushion behind my back, making me sit up straight for reading - I looked at my feet up in the air, because once again my buttocks sank into this supposedly medium firm sea of foam. I know I am supposed to sleep on this thing, but even stretching out on this soft foam you have to watch out not to suffocate because once again you are going under! the description says only the first layer is soft, well this thing is soft all the way to the bottom of it. Quite frankly, never have seen or laid upon such a piece of junk 'mattress' in my life, and I have slept on many. This thing is going back right away!

Mattress is decent and firm enough for my back. Was sleeping on an top of the line air mattress previously and it popped. Decided to get this mattress after looking at many others. 7 months pregnant and very supportive. It came right on time. Works for me.

We had this mattress less than 2 months and the foam warped and bulged and is sticking up inside the mattress. We are disappointed not only because we spent over $400 and the mattress lasted less than 2 months, but it would be entirely too difficult to return as it comes vacuum-packed in a bag/box and is quite heavy. Attaching pictures, although I'm not sure if you'll be able to see the warping. Buyer beware--this is a cheap item.
