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.

So my partner and I originally purchased this one mattress in 2020. At the time, it was the most incredible mattress with great support- we couldn’t believe it was only $400. After owning it for two years we noticed the mattress wears down a lot quicker than what a mattress should and wanted to exchange it thinking it just may be a minor defect. Sam’s club was kind enough to exchange it for us behind their member mark lifetime warranty guarantee. When we got the new mattress we immediately could tell that it didn’t feel the same as the original one we purchased. We have it it a chance thinking it just needed a few days out of the box but unfortunately it just wasn’t the case.

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.

I was a bit spectical at first about buying a Sam's Club (Member's Mark) branded mattress at such a low price. I've always had a Sealy, Serta or a Sterns & Foster. I figured that it wouldn't be any good. But I read the reviews and decided to give it a try and boy am I glad I did! This mattress is AWESOME!!! I've had two spinal disc surgeries about 4 years ago and finding a comfortable mattress, with the right support, has been a challenge to say the least. I've been sleeping on a $2,000 Sterns & Foster for the past 4 years that was supposed to be "top of the line" in comfort, but even that mattress doesn't come anywhere close the true comfort of this one. I purchased the Queen size at about 10 in the morning and even though on the Sam's Club website it recommends that you allow the mattress a full 48 hours to conform to it's full size, mine was fully conformed in a matter of a few hours. I was able to sleep on it that same night. It was the first fully restful night's sleep I've gotten since my surgeries. It's nice and plush, but not so soft that you sink into the middle of it. It's got just the right amount of firmness for that much needed support. I've always been a hot sleeper and I found this mattress keeps me at a cool level of comfort all night long. I don't think I can say anything else about it other than it's just a really good mattress, and for the price, you just can't beat it!

I had such high hopes for this mattress as I am a big time lover of the Members Mark brand.. however, this mattress did not prove its 4.5 star review. I tried to give it the benefit of the doubt despite seeing reviews about the mattress only inflating to 10 inches but that has proven true in my case as well. The edges of the mattress remained compressed and the cover fabric was loose due to the lack of foam inflation. Sadly I will be returning this mattress.

Stinks so bad! Literally like rotten garbage! This was for a kid's room, I don't want him breathing this! I have it in a bedroom upstairs and the entire 2nd floor stinks..it hits you halfway up the stairs! I have been happy with other Sam's mattresses..but never again. And since it's unpacked there is no way I can ever get it into my car to return it. Do not buy!

astronomical mattresses. Definitely choose this one over the new hybrid one. My entire household has these in all sizes. I bought my first one about 5 years ago and it hasn't had any impressions or imperfections. highly recommended. It has significantly reduced my lower back and hip pains. even the dogs love it

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.

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.

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.
