I love this bed! It's just the right level of firm that you feel supported but not rock hard like some firm mattresses. I was initially dubious buying sight unseen, but I ended up buying based on reviews, and boy I'm glad I did! The mattress comes flat packed and rolled up, and when I saw it I was concerned, but once it was out of the vacuum bag, it began to "pop" up and after a few days of letting it settle, it was great!
