Better than expected. I did NOT like memory form mattress because I prefer firmer mattress with steadily support. I hate the endless sinking feeling that my husband's old memory form had as well as others I have tried. But this memory form mattress from Sam's does not give me that sinking, unstable, wobble feeling when in bed. I choose firm and to me it's medium. But good enough. I think firm is ideal for face-up sleepers but less ideal for side sleepers. The remaining question is how long can it stay in shape without becoming too soft or even collapsing.

I love this mattress. We purchased it in Feb 2021 and I feel like I’ve given it plenty of time to have any issues and there are literally non that I can think of. I want 3 more of these. It is literally my favorite mattress in our house. Cannot recommend enough!

We hated this ultra plus mattress. It's like molasses for the top 3 inches then hard as a brick underneath, which doesn't work for a side sleeper with hips. Returning this has been a NIGHTMARE, 3.5 weeks of Sam's telling me someone would contact me to pick it up. Finally I get a call from some company I've never heard of and I have to wait another week. They were supposed to pick it up but waited to contact me that day to ask for a picture of the mattress. They finally showed up in some random pickup the next day. It's been 2 days and I still haven't been credited for my return. I've been calling Sam's all day and they keep hanging up on me. I contacted the company that picked the mattress up and they say they emailed Sam's, but Sam's acts completely clueless. Now I'm still fighting to get my money back and I'm absolutely furious because Sam's had a junk removal company pick up the mattress. They'd rather send a brand new mattress to the landfill then let me donate it to charity. We are so done with Sam's, they suck.

We're at day three on our Members Mark mattress, after returning a Casper mattress that we purchased. We found that the Casper was very stiff, and didn't breathe. On the flip side, this new mattress is super comfortable, and breathes well. It says cooling gel, but I haven't really felt cooling (It just has better airflow). For the price, I would recommend this to anyone.

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.

After much research we chose this firm, king size mattress. After originally leaning towards a hybrid mattress with springs and foam, we are extremely pleased with our all foam mattress. IMO, the addition of springs just adds an unnecessary quality risk with the way these "bed in a box" mattresses are packed. We had concerns about returnability and felt that a Sam's Club product (Members Mark) would be more highly supported in case there were issues. This mattress gives firm support, yet is comfortable whether a side sleeper or back/stomach sleeper. Without a legitimate firm mattress we are subject to back discomfort. After 7 nights of use we are happy to say that we are extremely pleased with our choice.

Do not buy if you have any form of back issues. I let fully expand before sleeping on it, I would wake through the night with lower back pain which isnt uncommon and reason why i bought bew mattress so i didnt think anything of it. By morning the pain is completely unbareable ive never experienced pain this bad. There is zero support with this mattress and is on the plush side nothing medium about it.

I purchased 2 Twin XL 12" medium mattresses to use with a King platform bed. While the mattresses expanded quickly, had no smell, and a perfect medium feel (not too soft/not too firm), they are not anywhere close to a Twin XL dimensions (38" x 80"). Within 15 minutes of unboxing, they each expanded to nearly 42" wide. Height only got to about 11" as well. 84" wide will not work on a 76 1/2" wide bed. I ordered online so they will be picked up, but it was a complete pain to have to plastic them up again for pick up.

It STINKS!! We’ve had it for 6 weeks and it still smells horrible. Hubby still hasn’t gotten his sense of smell back from Covid or I’m sure he would’ve complained. I unzipped the cover today hoping it would air out some and now the dang zipper is broken so I don’t recommend that! It’s super comfy and I don’t feel my wiggly hubby at all. I would recommend for comfort but the smell is bad. I’ve tried all kinds of things. Also the top layer of foam sort of wads up. You can’t feel it but it’s kind of annoying to see it.

this mattress is terrible. only expands to 10 inches. when you sit or lay on it, it goes down to 2 inches. then when you want to return, they'll send a fedx truck to get it, but then , you are with out a bed. so to try and fix the problem, i brought a 4 inch pillow top. more money down the tube. in short, its junk
