Mattress did have a chemical smell for a few days. It does sink at the edges when you get on and off the bed. It did take half-a-day to firm up. AND this mattress is the perfect balance of sinking into the mattress but not sinking too far. It's one of those mattresses that will not hurt your hip or shoulder if you stay in one position for hours. But you do not feel like you are on a hammock:) You feel like you are on a well made, expensive mattress that was a bargain!

I purchased this king mattress recently and am loving it!!! So comfortable and although quite heavy ( two people with strength should move and install)! There was no odor upon unwrapping it and it adjusted to final size rather quickly. I am going to be replacing another mattress at my home with this brand soon and I’ve recommended it to several family members.

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!

This indicates is medium firm but is by far the softest mattress I've ever had. I need a much firmer one. It also had lumps from not evenly expanding. I need to return it. Unfortunately, since I picked up in store instead of ordering online, I need to return it to the store. (The store was extremely rude when I asked about options.) One gal on phone told me to 'just roll it back up'... guessing she doesn't understand how these work :)

Bought 2 xl singles for our Member's Mark split king adjustable frame. The best sleep we have had in years! Very well satisfied with the mattresses and the frame. They are more comfortable than others we tried out at furniture stores that were triple the price!

Totally as advertised. It is a firm mattress. Motion transfer is minimal on a platform bed. We did end up using a plush mattress cover to soften the top just a little. Very happy with the purchase and the price. Delivery was quick. Follow directions on opening as it recovers shrink wrapped very quickly. We let it expand about 7 hours. Slept great the first night and every night since!

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.

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!

Sleeping in this bed felt like lying in quick sand. When you first sit or lie on it you think it feels firm but plush but then you continue to sink in further and further to where it's hard to move from one position to another. I hated this bed, I literally felt claustrophobic trying to move around in on this mattress.
