I bought this full size 12 inch high Membermark firm mattress from Sam's Club less than 2 years ago with an adjustable membermark base. I turned the mattress in all 4 positions but it lost its firmness and uncomfortable in flat position. I weigh 230 pounds. It has a 10 year warranty, but no idea how to act on it and with who.

We have bought two of these twin size beds. The first one was medium softness for my college-aged daughter. She loves the bed. The edges were a little too soft when sitting on the side of the bed, but super comfortable for sleeping. When my daughter moved out, we bought the same mattress in firm. I was worried the firm would be too hard, but it's perfect for me. So comfortable. You really can't beat the quality and comfort of these beds.

this mattress is high-quality and extremely comfortable and a great price. I even got up to the register and it was another $75 off as I could not believe it! I have a nectar mattress at home which I absolutely love but the quality of this is very comparable! For a third of the prize. Highly recommend

Sam’s Club actually stocks these. I was looking at a new mattress for my aging back. As well, I also was on a budget. This mattress is fantastic! It reduced my hip and back discomfort as well as reducing my tossing and turning at night. I’d recommend it!

I'm about 210 lbs., and unfortunately this mattress was far too soft for me. I sank deeply into it, almost like lying on a bag full of pillows, and it provided little support or the much-needed spinal alignment, actually giving me a sore back. Based on my experience, I would only recommend it for a much lighter person, perhaps under 150 lbs. If you are heavier or have back problems, I would strongly consider a more supportive hybrid mattress instead. The return process was also much more difficult than it should have been. Because getting the mattress folded back up and secured, down three stories, into my car, and to the Conroe Sam's Club was a major undertaking, I specifically called the Conroe location on September 2, 2026, at 10:55 a.m. (two days before my return date) to confirm exactly what was required for the return. I was told that I only needed to bring the mattress, the box and wrapping it came with, and my receipt. I had actually seen information online suggesting that the mattress might need to be completely wrapped in plastic, which is precisely why I called ahead to verify. However, the employee I spoke with specifically confirmed that, for their location, the mattress did not need to be sealed in plastic and that I could simply bring it back with the original box, the original wrapping in the box but not wrapped around the mattress, and my receipt. I work as an insurance adjuster, so paying close attention to details and exactly what is said is a routine part of my job, and I specifically recall the instructions I was given. However, despite what I had been previously told, when I arrived at the store, I was told that the mattress had to be fully sealed in plastic and taped and that I might have to take it all the way back home. After speaking with four employees and repeatedly explaining that I had followed the instructions their own employee gave me over the phone, a manager finally arranged for someone to come outside and wrap it so the return could be completed. Ironically, the male employee who came outside to handle it said the mattress was fine as it was. I ultimately received my refund, but only after a frustrating ordeal that could have been avoided had I been given the correct information from the start when I called. Back to the mattress itself, I would strongly recommend researching whether this type of all-foam mattress is appropriate for your weight and support needs, as well as confirming the return requirements before purchasing.

Bought this for my 2 years old. Toddlers need medium firm for their spine development. I waited 3 days to fully expand but It was still soft. It is softer than soft mattress. I am 240 lbs and when I sit side of the mattress I drowned all the way down to box spring. It is still okay for my 2 years old because she is only 35 lb but If we want to sit on it for putting her to sleep It is really annoying. So I returned and got the one with springs. My 3 stars goes to Sam's club customer service.

This mattress arrived quickly and packaged well. It arrives rolled up but opens up immediately when unpackaged. It is softer than I expected and sinks down more than I'd like when sitting on the edge. However, when you lay down on the mattress and your weight is distributed, it is very comfortable, as I learned from sleeping on it one night to test it. Unless you like a firm mattress, I would recommend this product.

Softer than advertised. Thought it would be more firm based on the scale on the details. But is soft. Needs to have a very solid box to be medium firmness. Good quality. Perfect dimensions. Easy to transport in box. Easy set up. It’s a good mattress. Just hoped it would be a little more on the firm side since I have back issues.

We have had this mattress in a queen size at our camp for the past few years. For our home we had so called very good mattresses ( at least by cost- lol ) that after awhile just didn't cut it. For the cost we bought these for our home. So far great. I expect these to be just as great as our camp set. It is next to impossible to judge a matress in the short term. Knowing the comfort of these matresses and the cost it was a no brainer.

Sleeps just as well as the 250 pound innerspring with plush pillow top 25 years old when it was new I think? Replaced the olympic queen. The 2 layers of coils were just fine but the foam wasn’t like new. This new queen inflated 98% in 3 minutes with no odor. Very happy with the purchase. Back not quite as stiff in the mornings. Doubt it will last 25 years but at this price who cares?
