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.

First new mattress in 20 years. Would give five stars but I have no reference for what a five star mattress would be. But I love this one. I would buy again. We mattress shopped locally first and decided to order this, due to the way better price and figured we would have to give up some quality. This mattress feels as nice as the $950 one at the store. We’ve slept very soundly without disturbing each other when one of us rolls over in our sleep. Very happy so far!

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.

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.

Brought Queen size this 3 weeks ago, mattress is still only 10" not what is says 12" in final size when it expands. Too soft even though the box and Website says Medium . the person next to you can make you role towards them :D I bought 2 other mattress before, i bought King and Twin was not this soft , it was medium as it was stated. liked it so i bought this , could be diffective from manufacturing! not sure. this may go back to store.

Convenient to purchase and quick to set up. Extremely comfortable and has great support for your entire body. Would recommend if you are looking for an inexpensive but high quality mattress that you don't need a pickup to transport. Loved the convenience of the bed in a box and being able to carry it up a narrow staircase.

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.

It starts with the unpacking. You will have to unwind layer upon layer upon layer of plastic - just great for the environment. First time I sat at the edge of the mattress I completely sank into it and my legs disappeared in the foam - I am only weighing 170 lb, mind you! Then I tried sitting at the top of the mattress, a large foam cushion behind my back, making me sit up straight for reading - I looked at my feet up in the air, because once again my buttocks sank into this supposedly medium firm sea of foam. I know I am supposed to sleep on this thing, but even stretching out on this soft foam you have to watch out not to suffocate because once again you are going under! the description says only the first layer is soft, well this thing is soft all the way to the bottom of it. Quite frankly, never have seen or laid upon such a piece of junk 'mattress' in my life, and I have slept on many. This thing is going back right away!

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.

The mattress is fine, but Sam's Club needs to read this: Fed Ex Ground is doing you a disservice. The drivers left my delivery on the street next to my garbage cans after hurling it from the truck. I made it home to retrieve it just before the garbage man was due and would have taken it as part of the trash pickup. Online sellers, Sam's, Amazon, Wayfair - all of you - need to hear this: Fed Ex Ground is a terrible carrier.
