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.

My husband and I have been using this mattress for the last 3 months. Compared to our old mattress, I love it! It’s great for relaxing and so nice to sit up and read/watch tv without getting uncomfortable. I do like sleeping on it, but I’d prefer it to be much more firmer. I was not sold on memory foam for this reason. My biggest complaint is that it says it has a cooling feature. We have a mattress cover on top, so not sure if that takes away from the coolness? My biggest issue is that we both wake up extremely hot. We like to sleep with the AC turned down, so if we forget to do that, we will wake up HOT and sweaty. Overall it’s a great mattress, but not sure if I’d purchase for myself again.

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 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.

Do not buy this bed If you are on the heavier side i weigh 280 my job provides a twin size mattress and i sink in completely there is no support and because it compresses so much there is no air flow so it becomes hot and uncomfortable this may be a good bed for thinner people i dont recommend if you are on the plus side

I cannot say enough good things about this mattress!! It is incredible to wake up with no pain! My husband and I are sleeping better than we have in years! Setup was easy. It does take a little time to allow it to fully expand (it comes compressed). There are no pressure points.

Just soft enough!

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.

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.

I guess our gust bed mattress was not exactly up to par. Ooops. Our daughter researched all the online foam mattresses and thought that this Member's Mark was the best quality for the right price. Set up was a snap. Really! After her first night on it, she described it as "amazing" . "Lifechanging" . She was not happy to report that it was better than her $2000 mattress at home. So, highly recommended!
