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!

King mattress purchased via pickup at local Sam's Club. First the box weight is about 80 pounds. The Sam's associate brought it out on a flat cart and didn't even attempt to load it in my truck. Never offered to help even as I stuggled to lift in the back of my truck. Got the mattress home and removed from box. Removed the plastic. I let it expand for 72 hours. It seem the cover is bigger than foam. When we put it on the bed the cover bunched up and was very loose.

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.

This is the second foam style mattress that we have purchased. We have the King Serta 12" Sleep-To-Go mattress in our master bedroom, which we really like and have had for over two years (also purchased at Sam's). We wanted to save money on a mattress (queen) for a spare bedroom, so we went with the Members Mark brand this time. It was pulled out of the package yesterday early afternoon, but after about 8 hours of expanding, it still appeared very lumpy. The edges are not expanding much and the mattress appears to be closer to 8-9", not 12" as advertised. I opted to sleep on the new mattress last night to test it out. This morning when I woke up, I felt I was sunken half-way into the mattress. I'm 6' and 215lbs. I've never had any issues with other mattresses in the past. The mattress is VERY soft, nowhere as firm or supportive as our Serta. I will give the mattress another 24 hours before returning it or contacting customer service to get any issues resolved.

I was in a financial and time crunch. I recently moved and had to purchase a matress quickly. Admittedly, I turned my nose up, assuming the store brand would not be comparable to the major matress brands. Bae-be was I wrong, wrong-wrong. This bed is firm like I like and applies the perfect amount of pressure to my lower back.

Love it!

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.

If you’re looking for quality sleep don’t hesitate to order this mattress. This review might be a bit premature as I’ve had the mattress less than a week, but I am impressed!! I will update my review if warranted but for now this mattress is 4 layers of pure heaven! Cool to the touch, very comfortable and fit on my existing box spring.

I love this mattress. We purchased it in Feb 2021 and I feel like I’ve given it plenty of time to have any issues and there are literally non that I can think of. I want 3 more of these. It is literally my favorite mattress in our house. Cannot recommend enough!

Good value
