It’s not at all what it’s described as. It does not feel cool at all as a matter of fact it gets pretty hot at night. Also it’s not very comfortable. I was told it expands a bit more as the 24 hrs hit well it’s still pretty thin and has this creases that stay once you lift it. When the mattress is set back to flat the creases remain on the mattress which in turn look like there’s something underneath the bedding once it’s made. Not to self go for the better brand even if it costs more

I have slept on a fair few beds in my life. All have been coil inside ones. I moved recently and needed a bed and opted for this one as it seemed reasonably priced. I waited a month round about to make any review on this bed. It is SO COMFORTABLE. I didn't read many reviews on it but what I did see was saying it was too firm or not firm enough. Look, if you like something that is gunna be plush FEELING but you don't sink a foot in to this is perfection! It took 48 hours to expand, once expanded it was some of the best sleep I've had in years. The adjustment period wasn't bad at all either, I did have some tension in my shoulders during it but that was just my body getting used to a more comfy bed than a harsh bed you can feel springs in. Warranty is good for 10 years and covers a 1in or greater dip in the bed. Seems good enough for foam beds since I've read that does happen to them.

The mattress is comfortable. I’m giving a rating of two stars because it wreaks of chemicals. It still smells just like it did the day it came out of the box and it’s been two months. The information pamphlet says it should stop smelling a few days after we unbox it. We have to air out the room daily.

I was a little bit on the skeptical side that this was going to be a 12 inch mattress when it came in. But after we got it out of the box and set up it lives up to its brand and description 100%. This was a new bed for our son's room (twin ultra plush) and he loves it. Sleeps so much better than he did on the old spring mattress. I would definitely recommend this mattress, it is very comfortable and easy to set up once it's out of the box it will take shape in 5 to 10 minutes. I love how easy it was to handle compared to a box mattress, like night and day. I do suggest getting a mattress cover or pad for it if you are buying for younger children since it is foam on top and will soak up everything.

This mattress is more comfortable than our temperpedic mattress that cost more than twice as much. I admit I was skeptical at first but the first time I laid down on it I was in heaven. We also purchased the adjustable frame and without a doubt they are a winning combination.

Couldn't have been better. Mattress arrived 7 days prior to expected delivery, and though the box was heavy, maneuvered it into bedroom, slid mattress out of box, lifted it on platform, and off it went, rapidly filling. Rapidly. Medium firm and looks good. Perfect for overnight guests and children

Supposed to be medium firm, but there is NOTHING firm about it! Sit on side and sink all the way down. At least 2 inches wider than normal king. Yes, we let it setup before use, but it only rose to 10 inches. Box said 12! Should be labeled extra squishy! I want my old mattress back! Totally disappointed with this purchase! Btw won't allow me to give zero stars!

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!

So I’ve only ever owned cheap spring mattresses they were way too firm and I’ve had back problems for as long as I can remember and I’m only 27. We got this mattress and I woke up so refreshed feeling. I need something that helps my pressure points and this did it! It does not sink me in but it curves to my body very lightly. I’m a side sleeper so this helped so much. I normally wake up with side pain and not anymore. Never woke in the middle of the night like I normally do. Both my kids have memory foam already but they’re twin mattresses so when we are ready to upgrade them I’d love to buy them the Members Mark one!! I never had any issues with a smell like the other reviewer and I only waited 24 hours it got up to 12 inches immediately but I still waited a day. Thank you Sam’s for selling an affordable comfortable mattress!

I took a chance by reading all the great reviews. Well that chance was a gamble I lost. Where do I start. First I let it air out for 72 hrs 24 more hrs than recommended and it still never fully inflated. Second this mattress is totally uncomfortable. I’ve slept on cots while deployed that was more comfortable. This was $400 plus bucks down the drain that I couldn’t afford. You live and you learn.
