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!

When we were looking at the matress selection at Sam's we couldn't find Soft type mattresses in store that would work with adjustable bed frame. We ended up on going with this medium firm Members Mark Hotel series and it turned out to be exactly what we wanted being that it's in a box and you can't try it out in store it actually was softer then what we pictured and for a side sleeper you feel nestled into the matress rather than on top and using pillows to get support its so nice what a difference it makes to sleep better.

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.

First it did not raise to 12" . Almost 11". The mattress is super soft and it sucks you into it. When you try to get out it bottoms out to the frame. It's the most uncomfortable mattress to sleep on. Sam's should be ashamed to produce this type of product. It's true, you get what you pay for as we thought we would try it out as we bought another brand similar to this and it lasted about 6 years and was very comfortable but that was not the case with this one. Don't waste your time taking this one home because you will be returning it. I hope they let us return it!

After reading the negative and positive reviews for this mattress, I decided to give it a shot because we were in desperate need of a replacement. This mattress is advertised as a medium-firm mattress, but it is NOT that whatsoever. This mattress is SOFT... so soft that your entire body will sink in if you weigh over 150lbs. If you’re into that, then it may work for you. But if you bought a medium-firm mattress because you prefer medium-firm mattresses, you will be highly disappointed. If you prefer firm mattresses and thought you might just settle for a “medium-firm”, then you may fall into a deep depression. Believe me before you waste your money like I did... this mattress is nowhere near medium firm, or even medium. Also, prepare to have your room smell like chemicals for several days. We off-gassed and decompressed this thing for an entire day outside and the smell is still giving me headaches. Here’s to hoping I can return this thing!

This mattress is a year old. I paid $399 for it. It has already broken down on one side under the weight of a 165 lb man who does not move a lot during sleep due to disability. I have mattresses on adjustable beds that are older and have not yet broken down under my weight or the constant up and down of adjustment. I'm not very happy.

I am extremely disappointed with the lack of free shipping for Plus members. It is unacceptable that despite paying for a Plus membership, this basic benefit is not provided. What exactly is the purpose of the Plus membership if it does not include essential perks like free shipping?

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.

Bed is really comfortable unfortunately it was deformed. Like other reviews, the end of the bed failed to to inflate to full capacity. Looks odd and also the top moves around when getting up. I’m contemplating returning but this would be the second bed in a box I return. Not sure it’s worth the hassle.

With mostly good reviews, my husband and I thought we would save some money and get a decent mattress from Sam's vs overpriced ones elsewhere. Man, were we wrong! When we first tried it out we thought "this is nice". It was softer than the medium-firm description. But the more you lay there, the deeper you sink. You get sweaty it's so hot. And uncomfortable. We had a crick in our neck the first few nights we slept in it (notice "in" it, not on it, because you are in this thing!"). You sink so low as your head stays on your pillow that your neck is in a very awkward position. We added a topper that helped some, but the mattress still sinks and sucks out topper in with it. It stinks right in the middle. We both wind up in the middle in this hole every morning. It's like a nest. A nest made by some gigantic bird that thinks we are its babies. If you like to sit up on your bed to watch TV or read, you can forget it with this one. Your bottom sinks in as you sit there and your little legs hang on to the top to keep you from getting completely devoured by the mattress. Reminds me of an old episode of "The Twilight Zone" or "Tales From the Crypt", I can't remember which one, but the bed was eating people. I really do not want to go through the hassle of trying to return this bed, especially because there is no way to get it back in the box. I don't live near by my Sam's Club either. On top of this mattress ordeal, they charged me twice for another item and can't take care of giving me a simple refund over the phone. They want me to drive sixty-six miles round trip to do that. I am very disappointed in customer service right now.
