After much research we chose this firm, king size mattress. After originally leaning towards a hybrid mattress with springs and foam, we are extremely pleased with our all foam mattress. IMO, the addition of springs just adds an unnecessary quality risk with the way these "bed in a box" mattresses are packed. We had concerns about returnability and felt that a Sam's Club product (Members Mark) would be more highly supported in case there were issues. This mattress gives firm support, yet is comfortable whether a side sleeper or back/stomach sleeper. Without a legitimate firm mattress we are subject to back discomfort. After 7 nights of use we are happy to say that we are extremely pleased with our choice.

We bought this for our oldest child a few years ago and it hasn’t been destroyed/ sagged and now this one for our youngest. So comfortable I’m thinking of trading our bed for this too. I have no back pain when I sleep on one of their beds. Only downside is if you like to sit on the edge of the bed, you will sink.

The mattress is fine, but Sam's Club needs to read this: Fed Ex Ground is doing you a disservice. The drivers left my delivery on the street next to my garbage cans after hurling it from the truck. I made it home to retrieve it just before the garbage man was due and would have taken it as part of the trash pickup. Online sellers, Sam's, Amazon, Wayfair - all of you - need to hear this: Fed Ex Ground is a terrible carrier.

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.

Comfortable little bed for now! Sleeping on a daybed after the move and had to order this twin mattress up really quick. Picked up with no issues from local Sam's Club. It has been a couple of weeks and it is actually really comfortable. It's going to end up in the office as a spare bed and I know the kids or even a single adult is going to be very comfortable sleeping on it for a few days or even an extended visit. I am most happy with the purchase and even debating ordering one for my bed or stepping up to the hybrid one for my bed. The price can't be beat!

Husband and I love this mattress. Let it completely fill before judging. It is a plush feel on top with a medium firm feel lower layer. No sinking in. We are both hard to please with mattresses and love this one. I am a side sleeper and hubby is a combo sleeper. Just works in all positions. Very comfortable! Way to go Sam's!

This mattress claims to be medium/firm. 100% not the case. I should have read the reviews because it is way too soft. To make a long story short, this is the worst mattress I have ever bought. Please don’t make the same mistake I did and purchase this bag of feathers.

I have purchased 4 of these over the last 2- 3 years and will continue to purchase them. I had my doubts based on the price point, but I was pleasantly surprised. I originally bought them for me kids and they liked them. I recently purchased one for my guest room and have slept on it the last 2 nights. I realize that I need to replace my own mattress after only 4 years because I slept so well on this one!

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.

We have 2 queens of this mattress and love them. We tried a queen first before buying a king size. Have been really disappointed in the king. The king size mattress is so soft and already has dents after 4 weeks of use. We used the queen for 8 months and didn’t have any of the issues we’re having with the king.
