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.

I thought that I wanted a softer bed but this is perfect. It is soft on top but you don't sink down in it. It does a great job keeping me in alignment. I have problems with my SI joint getting out of alignment and I usually have pain and night and have to keep shifting into different positions. But I don't have to with this mattress. I slept very well on it the first night. I also highly recommend the Member's Mark Premium adjustable base to go with it. It is amazing!!

Bought less than a year ago and is complete garbage. The matress already is sagging in the middle and if you lay to close to the edge you will roll right off because there is no structure to the edges of the mattress. Don't waste your money and can't return it because the store policy only covers the first 30 days. I would give it zero stars if I could.

I had such high hopes for this mattress as I am a big time lover of the Members Mark brand.. however, this mattress did not prove its 4.5 star review. I tried to give it the benefit of the doubt despite seeing reviews about the mattress only inflating to 10 inches but that has proven true in my case as well. The edges of the mattress remained compressed and the cover fabric was loose due to the lack of foam inflation. Sadly I will be returning this mattress.

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.

Love it! Great quality!

The manufacturing chemical smell has not gone away after letting this mattress air out with the windows open and no cover on it for 48 hours. With a waterproof cover, mattress pad, sheets and comforter, the room still smells and my hair even smells like the chemicals after sleeping in it. It's a decent mattress otherwise although you will slide off if you try to sit on the edge of it. It's very soft.

Fails over time. I have had this mattress for about a year and we are in the market for a new one. This mattress was great for about 6 months and then began breaking down to the point where I wake up in pain almost every morning. I contacted the local store I bought it from and they said I have owned it for too long for them to do anything so I would not really call that 100% satisfaction guarantee. It would probably be great for a guest bedroom or something that is not used daily.

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.

**** Full size, Firm **** If you’re looking for a firm mattress, this is not the one to buy. The mattress I received could be considered "medium" at best, which was a major disappointment. Unfortunately, my frustration didn’t end there—it only increased when I tried to return the item. I contacted Sam’s Club to request a return. Given the mattress’s size and that it had expanded after unboxing, I asked them to arrange a pickup. They agreed and scheduled one with AIT delivery service. But after more than three weeks, I’m still waiting for them to confirm a pickup time. During this period, I’ve reached out to Sam’s Club four additional times. Each time, they claimed that AIT had tried to call me, but I hadn’t answered—which isn’t accurate. I made sure to answer every call, and there were no voicemails left, which would have been expected if I missed a call. Sam’s Club also assured me that AIT would contact me by both phone and email, but I haven’t received any emails (I checked my spam folder too). It feels like there is a complete lack of coordination between Sam’s Club and AIT. In my latest conversation with Sam’s Club, they promised AIT would contact me within seven days, but at this point, I don’t have much faith in their word. My takeaway from this experience: Avoid buying any freight item from Sam’s Club. I had a similar issue with a previous Sam’s Club delivery, where a “white glove” item was simply left at my front door. Although they gave me a 10% refund for the inconvenience, I ended up spending more just to bring it inside and set it up.
