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!

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.

Buyers beware! This mattress is comfortable in the center, however mine never formed on the sides. We waited 52 hours to get on it but it never took. Since then I've been trying to get a refund or a replacement on it but sam's refuses to take care of it. They keep saying they need to pick it up before they will issue me a refund but THEY WON'T PICK IT UP. I keep calling over and over and over again to get it scheduled but they keep telling me i have to wait to be contacted. Sam's club online customer service is by far THE WORST customer service i have ever dealt with. For everyday purchases, Sams is great. But if you're looking to make a large purchase with a "warranty" i strongly suggest you buy elsewhere. Sams does not stand behind their product and they make it outrageously difficult to get help.

Comfortable

This mattress is a year old. I paid $399 for it. It has already broken down on one side under the weight of a 165 lb man who does not move a lot during sleep due to disability. I have mattresses on adjustable beds that are older and have not yet broken down under my weight or the constant up and down of adjustment. I'm not very happy.

I have slept on a fair few beds in my life. All have been coil inside ones. I moved recently and needed a bed and opted for this one as it seemed reasonably priced. I waited a month round about to make any review on this bed. It is SO COMFORTABLE. I didn't read many reviews on it but what I did see was saying it was too firm or not firm enough. Look, if you like something that is gunna be plush FEELING but you don't sink a foot in to this is perfection! It took 48 hours to expand, once expanded it was some of the best sleep I've had in years. The adjustment period wasn't bad at all either, I did have some tension in my shoulders during it but that was just my body getting used to a more comfy bed than a harsh bed you can feel springs in. Warranty is good for 10 years and covers a 1in or greater dip in the bed. Seems good enough for foam beds since I've read that does happen to them.

We hated this ultra plus mattress. It's like molasses for the top 3 inches then hard as a brick underneath, which doesn't work for a side sleeper with hips. Returning this has been a NIGHTMARE, 3.5 weeks of Sam's telling me someone would contact me to pick it up. Finally I get a call from some company I've never heard of and I have to wait another week. They were supposed to pick it up but waited to contact me that day to ask for a picture of the mattress. They finally showed up in some random pickup the next day. It's been 2 days and I still haven't been credited for my return. I've been calling Sam's all day and they keep hanging up on me. I contacted the company that picked the mattress up and they say they emailed Sam's, but Sam's acts completely clueless. Now I'm still fighting to get my money back and I'm absolutely furious because Sam's had a junk removal company pick up the mattress. They'd rather send a brand new mattress to the landfill then let me donate it to charity. We are so done with Sam's, they suck.

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.

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.

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.
