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!

Very Comfortable! I was a skeptical because it came in a "box" but this mattress is truly a great purchase! I ordered the firm king and it is just right! It has the right amount of firmness/softness (if you wlil). I am really enjoying it and so is my husband - who is very hard to please when it comes to mattresses! Thanks Sam's for a great affordable mattress!

Purchased this mattress about two weeks ago. Let it expand for 3 days and it has only reached 11 inches. The lack of height makes my sheets loose fitting. There is no support around the edges, so when you sit down on the edge of the bed, you slide off. For the price of 500 dollars I expected a little more....

This is not really a firm mattress. Some areas of the mattress are softer than others. Our backs have hurt every morning since the purchase of this mattress. I would love to return it but there is no way for me to transport a king mattress back to Sam's Club. It was delivered vacuum sealed in small box and then expands to full size.

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!

I bought this mattress in May of 2025. My grandchildren came and stayed a week in Oct of 2025. I have enclosed pictures of what the mattress looked like after that week, I could not iron the bumps down, I could not smooth the bumps down and they showed when the bed was made up. Look really tacky. I was shocked and surprised as Sam's products are usually some of the best. I always shop Sam's before going somewhere else. Sam's did send a pickup company to get the mattress and I did not have to take it to the store.

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.

I waited a month before posting a review just to ensure I gave myself plenty of time to get used to the mattress. I love it. It is so comfortable and I just feel my body relax every time I lay on it. My knees and hips no longer hurt when I wake in the morning -- I can only sleep on my side, so every day one or both would just ache all day. That hasn't happened since I purchased this bed. Excellent bed for the price and I'm really happy I purchased it.

We bought this mattress for our college aged daughter. It was so convenient to pick this up in a rolling box and bring it to her apartment. After cutting through the plastic the mattress was set up in minutes! It is a super comfortable bed. My husband and I may even buy one for ourselves. Great price!

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!
