This mattress is not medium. It's pretty soft and has no support. May be a decent mattress for a child or teen but a grown adult, no. I do not recommend.

I like the semi firm mattress. With that said, I would like to report 2 issues: 1. I ordered online, item came without original box, which is having wheels for easy movement. 2. Top part of the mattress is getting wavy after every use.

I have chronic back and knee pain. The first night I slept on this I was out like a light. It’s firm enough where you don’t feel like you’re sinking, but pliable enough that you feel like you’re laying on air. Amazing quality. We LOVE our mattress

I have purchased one in the past. This one did not fully expand in one corner. After 48 hours. And measuring its barely 10 inches. But comfortable. Price should be reduced.

Item was damaged it expanded once out of the box bigger than what can fit in vehicle. Customer service phone, online , and in person would not partial refund for damaged product

The mattress is quite comfortable. We have using them for only one week, but are adjusting to them quickly. They work well on our adjustable bed bases. Time will tell how durable they are, and remain comfortable.

The box said medium firm but this mattress is not even close to being a slight bit firm! I gave it 4 stars because although I wanted firm, this mattress made me realize that i don't know what i want! I love this mattress!!!

Bought this to replace a Serta Memory Foam, but it is not cutting it for me. I'm a small woman and already feeling an indentation just a few months in. We bought the medium, but I now I'm afraid to try the firm

So at first I saw “bed in a box “ and thought it would be too soft for my comfort. I was very impressed and still am a couple weeks later after my purchase. I highly recommend this bed to anybody with back problems.

"Firm" should not be in the description of this mattress. This mattress is not firm and does not have any support along the edge. I have purchased several mattresses from Sam's Club over the years, and this is the only one that disappointed me.
