This is a complete letdown. Bought a queen and two twins. All three of them have some weird bunched up sections on the tops. The twins expanded ok. The queen barely reached 10 1/2 inches. The sheets will not stay on at all because the bed is so thin and slippery. It is the most uncomfortable mattress ever. My body is in such pain. Dropped a load of money and disappointed.

This mattress is awesome! It’s firm but soft, the thickness is perfect... not too thin and not too thick. My sheets fit so I didn’t have to purchase anything new. It’s great! Easy to assemble and the smell was not that bad either. We set it up and gave two whole days to air out before we slept on it. Will definitely purchase this again if I need a new mattress in the future.

It works in a pinch. It's comfortable and firm, but very squishy on the edges. If you want a bed you can sit on the edge of, this is not it. For the price it's fine. I arrived earlier than expected, which was awesome. Can't go wrong with a Member's Mark item!

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.

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!

The reviews about it being too soft are correct. I have another memory foam mattress. Different brand. That is plush and isn't nearly as soft as this medium. It feels like you went to sleep on an air mattress and woke up in the middle of the night and it was flat. This is excessive. I like plush. But this is next level. It almost has me wondering if they put the wrong one in the box

Defective-as others have stated, it has a lump in the middle. Bought it for my guest room. Contacted Sam's through chat to find how to complete a return. They just said I needed to talk to the store. Store said I could put it back in the box (which is impossible) or wrap it in plastic. Then I get to stuff it into my car (which it won't fit in) and drive it back. I also don't live near Sam's so this whole thing is incredibly inconvenient. I tried to upload a picture, but this app only gives me an error message.

The bed came well packaged and very securely wrapped. As soon as I opened the packaging it completely sprung into shape with no issue. We're waiting a full 24 hours before laying on it. We ordered the medium and it's plenty soft and plush. I think it's perfect for my daughter but for me personally I would use the firm.

I bought a Nectar mattress at Sams Club and had to return it for a refund the following day. It was advertised as a Medium-Plush, but was so firm it was like sleeping on a cement slab. I had pain from pressure at several points on my body. I ended up buying this Member Mark memory foam mattress in the medium firmness, as there was not much to choose from at my club. Well, I can report that I am very happy I did. It feels so soft and comfortable, while at the same time being very supportive. I am comfortable on my back, sides, and stomach. No matter which sleep position I get into, I feel like I am sleeping on a cloud. I was pleasantly surprised I was able to get such a nice mattress for $400. It was $100 less than the Nectar and over $800 less than my previous mattress, which was not that good either. In fact, I had to use a memory foam mattress topper on it in order to use it. Thank you Sams Club for offering this great mattress!

I purchased 2 Twin XL 12" medium mattresses to use with a King platform bed. While the mattresses expanded quickly, had no smell, and a perfect medium feel (not too soft/not too firm), they are not anywhere close to a Twin XL dimensions (38" x 80"). Within 15 minutes of unboxing, they each expanded to nearly 42" wide. Height only got to about 11" as well. 84" wide will not work on a 76 1/2" wide bed. I ordered online so they will be picked up, but it was a complete pain to have to plastic them up again for pick up.
