Hard as A Rock. I like firm beds but woah! It smells Awful! Instantly smells of chemicals, whole house smelt awful. Had it unzipped and airing out still didn’t work. Returned!!!! Don’t waste money please.

We purchased this mattress on our son’s recommendation. He said this mattress surpassed any other bed in a box mattress he’s tried lately. He wasn’t wrong! Great mattress!!

We purchased this mattress for our RV. It is comfortable, not too firm but good support. I sleep well and wake with no backache. Only con would be the foam smell has taken a while to go away. The smell does not bother my husband though.

This is a really good mattress if you're looking for one on the firm side, it is super comfortable, back & shoulder pain are almost gone after less than a week.

This mattress contains FIBERGLASS. Below they stated they do not but we quickly learned last night that they do. My son, my husband and I woke up all itchy because of it. NOT OKAY

I bough a queen and a King they are both as hard as a rock, I was expecting something a lot better form Serta and It’s 10” not 12” they both are going back to Sam’s club. What a waist of time having to bring them back to Sam’s.

Very comfortable, does get hot/would recommend a serta cool mattress cover. Down side, mattress only expanded to 10” instead of 12” even after a wk & 1/2.

I bought this mattress 3 months ago and it's already sagging and soften. My back hurt so bad, I couldn't get up in the morning. I has 10 year warranty but only after 3 months it's sagging and deformed. Don't buy it or you'll be sorry.

Very happy with this mattress. I have purchased 2 kings and a queen. All have been perfect. It’s a firm memory foam which I find to be very comfortable to sleep on. Not too squishy like I’ve experienced on other brands.

Amazing products we were suspected when we saw that small box in our driveway, expecting a queen Mattress. But after reading the instructions and let it take place we are really satisfied this mattress is really comfortable
