First it did not raise to 12" . Almost 11". The mattress is super soft and it sucks you into it. When you try to get out it bottoms out to the frame. It's the most uncomfortable mattress to sleep on. Sam's should be ashamed to produce this type of product. It's true, you get what you pay for as we thought we would try it out as we bought another brand similar to this and it lasted about 6 years and was very comfortable but that was not the case with this one. Don't waste your time taking this one home because you will be returning it. I hope they let us return it!

It STINKS!! We’ve had it for 6 weeks and it still smells horrible. Hubby still hasn’t gotten his sense of smell back from Covid or I’m sure he would’ve complained. I unzipped the cover today hoping it would air out some and now the dang zipper is broken so I don’t recommend that! It’s super comfy and I don’t feel my wiggly hubby at all. I would recommend for comfort but the smell is bad. I’ve tried all kinds of things. Also the top layer of foam sort of wads up. You can’t feel it but it’s kind of annoying to see it.

King mattress purchased via pickup at local Sam's Club. First the box weight is about 80 pounds. The Sam's associate brought it out on a flat cart and didn't even attempt to load it in my truck. Never offered to help even as I stuggled to lift in the back of my truck. Got the mattress home and removed from box. Removed the plastic. I let it expand for 72 hours. It seem the cover is bigger than foam. When we put it on the bed the cover bunched up and was very loose.

Bed is really comfortable unfortunately it was deformed. Like other reviews, the end of the bed failed to to inflate to full capacity. Looks odd and also the top moves around when getting up. I’m contemplating returning but this would be the second bed in a box I return. Not sure it’s worth the hassle.

When we were looking at the matress selection at Sam's we couldn't find Soft type mattresses in store that would work with adjustable bed frame. We ended up on going with this medium firm Members Mark Hotel series and it turned out to be exactly what we wanted being that it's in a box and you can't try it out in store it actually was softer then what we pictured and for a side sleeper you feel nestled into the matress rather than on top and using pillows to get support its so nice what a difference it makes to sleep better.

Mattress is super comfy. I am 5foot 8 175 pounds and it is a perfect mid support mattress. I am a side sleeper and if the mattress is to soft or hard I wind up with back pain. I have had no pain with this mattress. It would be a 5 star but the workmanship on the mattress leaves a little to be desired. The cover you can tell was accidentally glued to the mattress in some spots causing the mattress to not rise completely. Also the cover is a little to large for the mattress making it too loose for the mattress. Like any foam mattress it smells awful for about a day or two till the smell goes away. If they can get the quality up just a little on the build it would be a 5 star

After getting an adjustable frame decided time to change mattress. Biggest problem was getting the old one off and ready for disposal and getting the plastic off the mattress was bit of challenge being careful not to cut the mattress. Once in place it began to hiss and start to expand quickly. Was surprised it only took a few hours to expand to 11 of its 12 inches! Very comfortable. Have seen reviews saying too soft but they must like sleeping on a rock as this is advertised as medium firm and would say that is right. So far so good and if run into problems in the future will come back to amend. So far very pleased.

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.

I bought this mattress in the Queen Size for my guest room. I was very skeptical to purchase a mattress online but decided to give it a try. I am really glad I did!! The mattress arrived on time and was packaged very well. The mattress expanded to 12 inches as expected. The mattress expanded to about 10 inches immediately and then the remaining 2 inches over the course of a couple of days. The mattress is a nice looking mattress. But most importantly my guests commented - The mattress is amazing!! They were very complimentary regarding the mattress and how comfortable it was. I have also slept on the mattress myself. Very nice mattress that offers a good support system. I highly recommend this mattress. I have no regrets.

We had this mattress less than 2 months and the foam warped and bulged and is sticking up inside the mattress. We are disappointed not only because we spent over $400 and the mattress lasted less than 2 months, but it would be entirely too difficult to return as it comes vacuum-packed in a bag/box and is quite heavy. Attaching pictures, although I'm not sure if you'll be able to see the warping. Buyer beware--this is a cheap item.
