I have had this mattress for a week. I bought a queen size for a guest room. My guest only slept on it for three days and it is already showing signs of wear. The top is wrinkled and crumpled up. Also, it never fully decompressed. One end of the mattress is still "squished". The name states it is a "medium firm" but it is not. It is very soft and you sink into it when you lay, or sit on it. I previously bought a queen size Sealy mattress in a box from Sams and I have been very pleased with it. I have slept on it every night for about three years and I love it. I would have bought another one this time, but my local Sams club was out of them, so I bought this one instead. A lot of the reviews said it was just as good but it is not. I am sadly disappointed and will attempt to get my money back.

I took a chance by reading all the great reviews. Well that chance was a gamble I lost. Where do I start. First I let it air out for 72 hrs 24 more hrs than recommended and it still never fully inflated. Second this mattress is totally uncomfortable. I’ve slept on cots while deployed that was more comfortable. This was $400 plus bucks down the drain that I couldn’t afford. You live and you learn.

Husband and I love this mattress. Let it completely fill before judging. It is a plush feel on top with a medium firm feel lower layer. No sinking in. We are both hard to please with mattresses and love this one. I am a side sleeper and hubby is a combo sleeper. Just works in all positions. Very comfortable! Way to go Sam's!

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.

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.

Mattress is far too soft you will end up with severe neck pains. The mattress has completely compressed and now I am experiencing both neck and back pains. This all even though I didn't sit or sleep on it for 72 hrs. after opening. This scenario is absolutely absurd and very disappointing

I feel like my bed never fully expanded, it’s supposed to be firm and it is the softest bed ever and not in a good way. I have tried to return but it is already is out of box in my apartment and I don’t know how to bring it back. Customer Support didn’t help me when I called :( help!

I guess our gust bed mattress was not exactly up to par. Ooops. Our daughter researched all the online foam mattresses and thought that this Member's Mark was the best quality for the right price. Set up was a snap. Really! After her first night on it, she described it as "amazing" . "Lifechanging" . She was not happy to report that it was better than her $2000 mattress at home. So, highly recommended!

I bought this bed because my Orthopedic Mattress was beginning to get too hard for my older body. I had sore shoulders and back. This was delivered to the door in a large box. It's bulky but manageable, I am 65 years old and managed to move to the first floor. Once unpacked it rapidly began to expand. I let it expand for 24 hours. It appears to be about half to one inch short of the 12 inches advertised. I have no experience with foam mattresses so didn't know what to expect from Medium Firm. Turns out it works well. My stiffness is slowly dissipating though it took me a couple of nights to get used to sleeping on a foam mattress. I didn't get the chemical smell some reviewers noted, I still have a pretty sharp sense of smell. After about a week I am pleased with the mattress. It's hard to beat the value of the Members Mark and return guarantee. I took one star off for the actual height being shorter than advertised.

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.
