Bought this mattress today. Opened it up and it puffed up right away. But then noticed the smell. It had all day to air out. It was so bad when we tried to sleep on it . At 2:30 a.m. we were up dragging it out of the bedroom. We put cot mattresses on the floor and slept on them. We will be returning this as soon as the store opens. Even with the mattress out of the room we could still smell the fumes.

This is way more comfortable than the old fashioned box spring and mattress. I was very impressed with the level of comfort and support. My son loves it- it really exceeded all of my expectations which were already pretty high based on reviews I had read prior. Great item for the price!

Defective-as others have stated, it has a lump in the middle. Bought it for my guest room. Contacted Sam’s through chat to find how to complete a return. They just said I needed to talk to the store. Store said I could put it back in the box (which is impossible) or wrap it in plastic. Then I get to stuff it into my car (which it won’t fit in) and drive it back. I also don’t live near Sam’s so this whole thing is incredibly inconvenient. I tried to upload a picture, but this app only gives me an error message.

This is a complete letdown. Bought a queen and two twins. All three of them have some weird bunched up sections on the tops. The twins expanded ok. The queen barely reached 10 1/2 inches. The sheets will not stay on at all because the bed is so thin and slippery. It is the most uncomfortable mattress ever. My body is in such pain. Dropped a load of money and disappointed.

I bought this mattress after sleeping on a 1k Serta fancy all the bells and whistles and mattress for the last 5 years. I have never slept better in my life. It is a spiritual experience climbing into this bed every night. I have to fight off my children who try to climb in to our bed every night as well. It’s a neat lesson on physics too, during these homeschooling times.

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.

We purchased a full-size, firm mattress for our spare room in February. It's now June. I waited to leave a review, so I had plenty of time to try it out. It is definitely not firm. I sleep on it 5 nights a week. It's soft, and your body sinks. It might be firm for a child, but anyone over 100 pounds would not say it's firm. Would not recommend or buy again. .

I really wanted to love this mattress, but I don’t. I ordered it in early December 2025, and have slept on it for a month and a half now and I just hate it and really regret getting a memory foam mattress, and an ultra plush one at that. I cannot get comfortable. No matter how I lie, be on either side, my back, my stomach, kind of on my side and stomach, I cannot get truly comfortable. I can’t sleep well either on account and I think I’m averaging about two to four hours of sleep per night. Getting off of this bed is so difficult and I messed up my right knee getting up and down off this bed that I had to barrow a walker from my 90 year old neighbor (I just turned 48!) because my knee was so painful and strained and trying to give out on me from getting up and down off the mattress. My lower back and hips are also always extremely stiff and sore now after nearly two months of ‘sleeping’ on this mattress. I’m now going to lol for a hybrid mattress and spend yet more money to replace this one that I can’t enjoy.

I orginally purchased one of these beds with the adjustable base for my mother when she went into independent living. She absolutely loves it and my kids also love resting on grandma's bed. When we moved and my girls had outgrown their bunk beds, I bought two more. So, everyone loves their beds!

Bought this at the end of may and here we are in July. Still has the chemical odor smell. In order to take it back, you have to have the box and be able to get the expanded mattress to the store. A bit ridiculous! Waste of 400 bucks. And this is the second bed from there that stinks. We bought a king bed the month before. So much for using membership perks to get a quality bed. Very disappointing considering the promises of satisfaction! Not satisfied. Not happy. Not renewing my membership.
