Defective mattress. Less than a week mattress cover bunched up 4 inches across center of mattress. Then you have this hump in the middle of the bed under your back. Will be returning when different replacement mattress (ordered) is received. Also if you return a mattress they want you to put it in the original box (not gonna happen) or wrap it in plastic.

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.

Mattress is very comfortable - softer top with firm support. A high quality mattress that doesn't break the bank. It was easy transport since it comes in a box. Be sure to have the box spring/platform bed ready for the mattress because once you unravel and cut open the plastic it is heavy and harder to move around then when in a box :)

I redecorated my son's room and was originally looking for a mattress topper to bring life into a VERY OLD mattress. A quality topper is pricey and I figured it would be a temporary fix which would ultimately lead to a new mattress sooner than later. I stumbled upon this Member's Mark mattress at my local Sam's club during my topper hunt. The price was double the price of a nice topper, so I decided to skip the topper and go straight for a new mattress. After a couple of days of expanding, it is really nice. My son only comes home from college occasionally, so it is a perfect addition to his room. Personally, I like a firm mattress, but when I lay on this one to test it out, I'm pleasantly surprised at how comfy it is. My son loves the way it sleeps and never complains any more about coming home and staying for a while.

Bought this bed because of the mostly good reviews, but honestly none of them ever mentioned weight and how it felt for bigger people. Do NOT buy this bed if you’re overweight or on the bigger side. You’ll sink right into it. It’s not firm in the slightest for someone oversized, and you’ll have a hard time getting out of it. I started noticing it dent in the middle right away, which sucked for me cause I’m a stomach sleeper. Plan to return it as soon as I find a more suitable bed for myself.

I have purchased more than 7 boxed memory foam from Sam’s or Costco. This mattress was packaged beautifully, sprang up when opened and had far less of the chemical smell than previous mattresses. I gave it 24 hours to rise, but the morning after I slept on it I had new pain in my hips, knees, elbows and shoulders...I’m 5’5, 130 lbs and 40 years old. This type of pain was a first! I tried it again for 2 hours the next night and moved to the sofa. For whatever reason this particular members mark hotel collection mattress was too firm for me. In the store I sat on Serta’s bed in a box version and it was far softer but was unclear if that was its composition or if it had been broken in by other consumers. I purchased the members mark mattress because they produce great products and I wanted to give them a shot. Luckily I was able to track down my receipt from my previous mattress also purchased at Sam’s by Night Therapy and ordered it as a replacement. I purchased a mattress bag to protect the members mark mattress in the return process, but when I called to double check they were accepting return due to covid they told me Fed Ex would pick it up! The associate on the phone couldn’t have been more helpful immediately credited my card and arranged Fed Ex pick-up 2 days later. I had a terrific experience even though this bed didn’t work out for me!

Have been hunting a mattress for years that would allow me to get a good nights sleep. So tired of waking up hurting and not rested. Have had trouble for years waking up because I just couldn’t rest. I don’t have that problem anymore. This is the absolute best mattress I’ve ever slept on.

This is a really nice mattress. It's the queen medium version. I was able to pick it up the same day I ordered it. As a person born the middle of last century, I was able to get the box out of the car and into the bedroom without too much trouble. Getting the box on the bed & the mattress out of the box was more challenging by myself. I was so tired after that, that I just went ahead & very very carefully cut thru the wrapping. The mattress popped right out & started expanding right away. It was easy to turn & position the mattress. As others mentioned, it does smell at first, I left my air filter for 3 days before I used it. As an asthmatic, I was just being cautious. I have the medium version and it is not overly soft, it is not as soft as what I used to have. I love it. There is just enough softness to be very comfortable and firm enough that I slept thru the night. I love it. I do have a fluffy mattress cover on it since I have an elderly cat that sleeps on the bed too. Getting in & out of the bed is easy & being able to easily scoot to the middle is really easy & nice. I would love to see how it was squished, rolled, wrapped & stuffed in the box. My only problem is getting rid of the old mattress.

Great mattress, first time on anything before with springs. 2 back surgeries and 5 mattresses later, THIS one is letting me get some sleep finally. I don't know who the people are that read this , but if you have back problems, this one so far has done a good job.

The 12 inch twin mattress that I purchased at Sam's Clubis false advertisement the box said it was a 12 inch mattress and it is not it's 10 1/2 very disappointed. I am 65 and a widow. I cannot afford to hire someone and rent a truck to return it so I'm stuck with it. Mattresses in the spare room and I have one it says got it for 10 days and it's still not inches 10 1/2.
