After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

Ultimate comfort from a mattress that is delivered rolled up. I’ve purchased others, brand names, and nothing compares to this mattress. Priced right at about $200- for the twin size, I needed a mattress that would be on a platform without a box spring. This is the one, at 12 inches thick it has great comfort and support. You need to open it and let it air out from the factory smell, which only lasts about a day, also giving it time to fully expand. Great purchase, great quality, pleasant dreams!

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.

This is the second foam style mattress that we have purchased. We have the King Serta 12" Sleep-To-Go mattress in our master bedroom, which we really like and have had for over two years (also purchased at Sam's). We wanted to save money on a mattress (queen) for a spare bedroom, so we went with the Members Mark brand this time. It was pulled out of the package yesterday early afternoon, but after about 8 hours of expanding, it still appeared very lumpy. The edges are not expanding much and the mattress appears to be closer to 8-9", not 12" as advertised. I opted to sleep on the new mattress last night to test it out. This morning when I woke up, I felt I was sunken half-way into the mattress. I'm 6' and 215lbs. I've never had any issues with other mattresses in the past. The mattress is VERY soft, nowhere as firm or supportive as our Serta. I will give the mattress another 24 hours before returning it or contacting customer service to get any issues resolved.

I have had this mattress for a week. I bought a queen size for a guest room. My guest only slept on it for three days and it is already showing signs of wear. The top is wrinkled and crumpled up. Also, it never fully decompressed. One end of the mattress is still "squished". The name states it is a "medium firm" but it is not. It is very soft and you sink into it when you lay, or sit on it. I previously bought a queen size Sealy mattress in a box from Sams and I have been very pleased with it. I have slept on it every night for about three years and I love it. I would have bought another one this time, but my local Sams club was out of them, so I bought this one instead. A lot of the reviews said it was just as good but it is not. I am sadly disappointed and will attempt to get my money back.

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 a cal king a year ago and am extremely happy with this mattress. I'm a side sleeper and found it a bit firm, even in ultra plush, but I bought a Serta memory foam-and-"fluff" mattress pad, which made it exquisitely comfortable. Now the mattress and sleeping is perfect and absolutely delightful for me. I love getting in the bed, so look forward to those few minutes of enjoying the mattress cushy comfort before drifting off to sleep. My 75 pound dog jumps up in the night and I don't feel it at all. I only know she did it because she is still there in the morning. LOL Will buy another, smaller, when I relocate in a couple months. You can not beat this for the price. I couldn't be any happier with it. Seriously

I have purchased the Serta mattress at sams and the quality is way different. This mattress is very weak around the edges and the corners are worse. If you are using a platform bed that is slatted the mattress will push right through so you will need some kind of support between your mattress and the slots. I would recommend the serta bed in a box over this one for sure.

I read other reviews and thought I could get away with some of the issues noted about this mattress but no. This is error purchase for me. The mattress is softer than the mattress I'm trying to haul. I literally sink into this mattress. I was expecting medium firm but it's not near it. Planning on returning it. My old mattress lasted over 10 years, not sure this new mattress would make half of that. I brought on sale so i'd say penny wise, pound foolish. Cheap is expensive! Also gives me heat not cooling at all, makes me uncomfortable overnight.

I bought this mattress about a month ago, and it doesn’t show up in my order history so I can’t return it. Hmm weird. Secondly, this is advertised as medium firm, if you go to any mattress store and feel what a medium firm mattress is, this is NOT it. This is the plushiest mattress I’ve ever owned. If you’re looking for any level of firmness, buyer beware! Would return but the order is mysteriously missing from my account.
