I gave it a 4 because the sheets will not stay on the corners. I am not a bad sleeper by any stretch. I used to go to sleep and the other side of the bed would still be perfect. Now for some reason the corner always come unfasten. It arrived compressed, once you cut the plastic, it expands. Place it on the frame before removing the plastic. That is my only complaint is about the corner, other than that it is perfect.

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!

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.

Extremely comfortable from the start. Less than $500 on sale. Heavy and sturdy. Medium/plush feel. Added a plushy mattress pad, all cotton members mark hotel premier sheets, and bamboo pillows. The bed felt better than diamond hotels. It is set up on a guest house so it will be used sparsely, but I will update on longevity if anything goes wrong.

I give 1 star because I’m sure other people like it that soft but I expected it to be a little firmer for medium firm, but it was so soft you sank so far in it hurt my back when laying on my stomach. The smell was just plain god awful and didn’t go away even after airing it out for over 48 hours with windows open in the room. The smell gave me migraines as well as made my sinuses hurt. We returned the bed and ordered one of from Walmart that has been much better.

I love this mattress! It is so soft and comfortable. It came in a box and I was able to keep it in the box until I was ready to put it in place. Getting it out of the box and unsealed took a little bit of work doing it by myself, but with two people it shouldn’t be an issue.

Brought matress home, took it out of the box, unfolded it, and then start to cut the plastic off of the mattress while it inflated. Stopped immediately when I noticed there was mold/mildew growing on the bottom of the mattress. I was very happy that we had not already taken our previous mattress to the curb. The end of the mattress that had the mold/mildew also did not inflate correctly by the time we took it back to Sams Club the next day. At least the return was easy!

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.

My daughter got this bed recently and loves it. I bought it for my spare room and my brother-in law who is a big guy, has been staying in there, also loves it. Now I'm buying a full size for the other spare bed. I'll see what my guests say when they come to visit.

The mattress is comfortable but sleeps hot. The mattress height has yet to decompress to the full 12" height in the advertised description. The width of the mattress budges obviously by 2"-3" overall. I will be returning this mattress as soon as I am refunded for the mattress I purchased online through Sam's Club. Today is the 9th business day since my online return was picked up. The online return pickup process was a pain staking 45 days. Sam's Club Members beware!
