I was a bit spectical at first about buying a Sam's Club (Member's Mark) branded mattress at such a low price. I've always had a Sealy, Serta or a Sterns & Foster. I figured that it wouldn't be any good. But I read the reviews and decided to give it a try and boy am I glad I did! This mattress is AWESOME!!! I've had two spinal disc surgeries about 4 years ago and finding a comfortable mattress, with the right support, has been a challenge to say the least. I've been sleeping on a $2,000 Sterns & Foster for the past 4 years that was supposed to be "top of the line" in comfort, but even that mattress doesn't come anywhere close the true comfort of this one. I purchased the Queen size at about 10 in the morning and even though on the Sam's Club website it recommends that you allow the mattress a full 48 hours to conform to it's full size, mine was fully conformed in a matter of a few hours. I was able to sleep on it that same night. It was the first fully restful night's sleep I've gotten since my surgeries. It's nice and plush, but not so soft that you sink into the middle of it. It's got just the right amount of firmness for that much needed support. I've always been a hot sleeper and I found this mattress keeps me at a cool level of comfort all night long. I don't think I can say anything else about it other than it's just a really good mattress, and for the price, you just can't beat it!

I cannot say enough good things about this mattress!! It is incredible to wake up with no pain! My husband and I are sleeping better than we have in years! Setup was easy. It does take a little time to allow it to fully expand (it comes compressed). There are no pressure points.

Stinks so bad! Literally like rotten garbage! This was for a kid's room, I don't want him breathing this! I have it in a bedroom upstairs and the entire 2nd floor stinks..it hits you halfway up the stairs! I have been happy with other Sam's mattresses..but never again. And since it's unpacked there is no way I can ever get it into my car to return it. Do not buy!

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.

We bought this mattress maybe a year ago to replace a 15 year old mattress. At first we loved it but it quickly went down hill from there. We let it set up for a full 48 hours to lay on it and the first month was nice. Then to my surprise the middle started sagging and BAD. After numerous spins over the last few months this mattress is almost unusable as the center sinks so bad that my fiancé and myself wake up basically on top of eachother every single morning and with worsening back pain each day. Absolutely do not suggest this mattress and am currently looking into their “10 year warranty” they advertise

The manufacturing chemical smell has not gone away after letting this mattress air out with the windows open and no cover on it for 48 hours. With a waterproof cover, mattress pad, sheets and comforter, the room still smells and my hair even smells like the chemicals after sleeping in it. It's a decent mattress otherwise although you will slide off if you try to sit on the edge of it. It's very soft.

Bought less than a year ago and is complete garbage. The matress already is sagging in the middle and if you lay to close to the edge you will roll right off because there is no structure to the edges of the mattress. Don't waste your money and can't return it because the store policy only covers the first 30 days. I would give it zero stars if I could.

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!

Supposed to be medium firm, but there is NOTHING firm about it! Sit on side and sink all the way down. At least 2 inches wider than normal king. Yes, we let it setup before use, but it only rose to 10 inches. Box said 12! Should be labeled extra squishy! I want my old mattress back! Totally disappointed with this purchase! Btw won't allow me to give zero stars!

Good value
