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?

My Son is enjoying his new comfy, all in one mattress!⭐️⭐️⭐️⭐️⭐️Five stars for the detail this option provides. There’s zero need for a boxspring. We ❤️Love it!

First time I have purchased a mattress that did not require a box spring. I thought it looked a little thin it was for a guest bedroom. However guest said it slept nicely.

I’ve bought mattresses with Sam’s before but never the member’s mark brand. Exceeded my expectations and will buy the same style in the future for guest rooms.

Ok for the price if you don’t care if it’s truly a 12” mattress. Had it open for 5 days and never inflated to the 12”. Was about 10-1/2”. Smell didn’t dissipate either. Returned this item.

This is a good quality mattress for someone who likes a soft bed, this was for a guest bed but it would not be my choice personally as I prefer a firmer mattress. Good bang for the buck though!

I sleep so much better on this mattress! I had been sleeping on the same mattress for 15 years. I was much needed for an upgrade. I have gotten some of the best sleep I've had in years lately. And I love that it also keeps me cooler at night.

This is the perfect mattress for my 6 year old daughter. She is always saying how comfy she is when she is laying on her new mattress, I have slept with her on some occasions and got the best rest too.

This mattress is very comfortable I love my bed I just had knee replacement it feels wonderful with the adjustable bed frame and the price is reasonable

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.
