I cannot say enough good things about this mattress!! It is incredible to wake up with no pain! My husband and I are sleeping better than we have in years! Setup was easy. It does take a little time to allow it to fully expand (it comes compressed). There are no pressure points.

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.

Medium firm purchased, its way to soft, zero support. I am so disappointed, my 10 year old mattress was way better. I threw away the packaging so return is out of the question and even if I had it how do you roll it back into the box? Mission impossible.

Adequate for guest room. Too soft for me—I do like firm mattresses though. Convenient in the box. Shopping experience was awful though. Well—cashier was—rude!! And very strange—there was a music speaker on the floor that I almost tripped over. Playing loud music. I lowered the music and the cashier got aggressive about that. Just a strange experience.

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.

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.

The musty chemical smell is has been just absolutely horrible. I have been sleeping on this mattress a month and it still smells. I'm have been waking up with headaches since day one from the smell. Plus with the poor support you sink down in it to far. I don't recommend this Hotel 12" Premier Queen mattress and I would love to return it!

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.

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.
