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.

Bought this for the reviews, it is NOT FIRM at all. Actually going to return it. Not sure on the great reviews. If you want soft and squishy and back breaking go for it. NOT FIRM, returning it due to so soft I am crippled. I ordered firm for a reason and this is not it.

Medium firm purchased, its way to soft, zero support. I am so disappointed, my 10 year old mattress was way better. I threw away the packaging so return is out of the question and even if I had it how do you roll it back into the box? Mission impossible.

The mattress is comfortable. I’m giving a rating of two stars because it wreaks of chemicals. It still smells just like it did the day it came out of the box and it’s been two months. The information pamphlet says it should stop smelling a few days after we unbox it. We have to air out the room daily.

Bought this at the end of may and here we are in July. Still has the chemical odor smell. In order to take it back, you have to have the box and be able to get the expanded mattress to the store. A bit ridiculous! Waste of 400 bucks. And this is the second bed from there that stinks. We bought a king bed the month before. So much for using membership perks to get a quality bed. Very disappointing considering the promises of satisfaction! Not satisfied. Not happy. Not renewing my membership.

I had such high hopes for this mattress as I am a big time lover of the Members Mark brand.. however, this mattress did not prove its 4.5 star review. I tried to give it the benefit of the doubt despite seeing reviews about the mattress only inflating to 10 inches but that has proven true in my case as well. The edges of the mattress remained compressed and the cover fabric was loose due to the lack of foam inflation. Sadly I will be returning this mattress.

2 months after purchasing this mattress it began to sag in the middle. 2 people sleeping in this bed wind up laying up against each other in the center of the mattress. THEN - since I can't read "fine" print - SAMS CLUB will not allow me to return the mattress because I threw away the box. THEY REQUIRE YOU TO BRING IT IN FOR THEIR 100% MONEY BACK GUARANTEE WITH THE ORIGINAL BOX. I am so disappointed in the mattress and SAMS CLUB. WHO KEEPS A BIG BOX STORED JUST EXPECTING A TRUSTED STORE LIKE SAMS WOULD SELL THEM SOMETHING CRAPPY THAT THEY WOULD NEED TO RETURN IN THE FIRST PLACE.

I was very disappointed. This bed was warm and worse way too soft. It was so soft the sheets were constantly popping off. After calling Members Mark and trying it for almost two months this bed had to go back to the store. Check out the new Casper line… Im MUCH happier.

I was a little bit on the skeptical side that this was going to be a 12 inch mattress when it came in. But after we got it out of the box and set up it lives up to its brand and description 100%. This was a new bed for our son's room (twin ultra plush) and he loves it. Sleeps so much better than he did on the old spring mattress. I would definitely recommend this mattress, it is very comfortable and easy to set up once it's out of the box it will take shape in 5 to 10 minutes. I love how easy it was to handle compared to a box mattress, like night and day. I do suggest getting a mattress cover or pad for it if you are buying for younger children since it is foam on top and will soak up everything.

Mattress is decent and firm enough for my back. Was sleeping on an top of the line air mattress previously and it popped. Decided to get this mattress after looking at many others. 7 months pregnant and very supportive. It came right on time. Works for me.
