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.

Mattress sleeps well but after a couple of nights of sleep we noticed a wrinkle in the mattress/ fabric all the way across the middle of the bed. So now when we sleep on it you can feel the wrinkle underneath it. They sent a replacement, it done the samething.

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.

Love it!

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

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.

So compy! Love it.

The mattress is comfortable. I’m giving a rating of two stars because it wreaks of chemicals. It still smells just like it did the day it came out of the box and it’s been two months. The information pamphlet says it should stop smelling a few days after we unbox it. We have to air out the room daily.

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.

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!
