Very comfortable. Im sleeping so mich better than i used to. Our old bed was sinking down about the time we bought this (right before we bought this one). Once it expanded we havent had any problems. Even comfortable after surgery.

I ordered a queen firm mattress and it is not firm at all and has not inflated properly and it’s been up for three days. I am very disappointed. It is saggy and lumpy and looks like I have had it for 16 years instead of three days.

There shouldnt be any bad reviews for this mattress..it does just what its supposed to Right out of the box instantly more than 12 inches on every side...and soft yet firm just right My daughter and I love it...perfect mattress at a good price

I used to sleep with a heating pad under my hip, but since i got the Members Mark foam mattress i am so comfortable i don't need one to sleep without pain.

Although the mattress is advertised as 12 inches, mine has only reached 10.5 inches and it's been 5 days. Other than that I do feel like it's super comfy! But since it's not expanded fully it's not sitting on my box spring correctly

While it’s described as medium firm, it is actually very soft. That said, it is also quite comfortable. So for the price it was a good purchase but I’d remove the word firm from the definition. Longevity?

Love this bed! We had a sleep number for 20+ years and needed a firm mattress, this is just as good and a great price! Plus you just open up the box and the bed is ready in a few hours!

It’s a great bed, supportive but comfy right out of the box. It’s thick so your base can be short. It is “firm” so not pillowy but still very padded on the top. I ended up buying a second twin sized one for my guest room.

After 30 years of expensive mattresses, I decided to give this a try. I usually use a firm mattress with an additional foam topper so I purchased the medium and it’s perfect. Snuggly on top with good support underneath. Great value.

Nice mattress. Bought for my son and his initial reaction was “Will it flatten out?” And then “it’s too soft” but it turned out perfect. He’s very happy.
