it is Very Hard with only a little give, easy install comes in a box rolled up. if you firm beds this is a great one for you!

I wish I would of believed the reviews, not sure what it is but this mattress is firm yet it sinks half your body. Hard to explain, when we wake up our backs are so sore. I really regret getting rid of our old one for this. Wasted money

I have had this mattress just over a year. A couple months ago it started sink in the middle, causing you fall towards the middle of you sleep on one side. This makes it very difficult to sleep.

This mattress is wonderful, I'm able to sleep again, works well with my kids since they move a lot I'm stable to sleep well when they are in bed with me. Is comfy, cozy, stable. Love it!

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.

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.

We tried this mattress but had to return it after the second night. It was like sleeping on the floor. Sam's Club gave us no problems with the return.

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.

I weigh about 450lbs. I usually wake up every 1 1/2-2 hours in my old mattress. Since day one I've slept through the night peacefully waking up only once a night.

We were not sure how a matress in a box would be, but have been quite happy with it. We don’t wake each other up when getting up at night and it is very comfortable.
