We have been using the

We have been using the new bed for 3 weeks and it is much firmer than our previous pillowtop mattress, but we no longer have backaches due to the sagging old mattress, which was the reason we were looking for a new bed. The top layer I believe is memory foam which after lying in bed for a short time seems to conform to your body making it more comfortable.

It’s been the best sleep

It’s been the best sleep I’ve ever had. Casper is the best company around and I will never buy another mattress again, because Casper has my back, literally. The best sleep of my life, and I rest assured.

We love our Casper mattresses! They are the most comfortable beds we’ve ever had, and we bought one for my daughter when we got her a bigger bed. She loves it!
