I was at first disappointed with the Casper Mattress. It was too soft for me. Then I decided to replace my mattress pad with the Casper Mattress Protector. Wow, what a difference!  Not only does it protect the mattress, it provides some additional firmness that for me is just about perfect. So if you're like me in thinking that the Casper Mattress is a bit too soft, try adding the mattress protector. It really helped for me.
