The One is Great
I’ve been sleeping on the new mattress for a couple of weeks now. It’s very comfortable and I rest so much better. Great mattress. Would highly recommend.

Amazing Mattress
We received our Casper 1 and love it. It is on the firm side and that is what we wanted. We are looking forward to many great nights sleep with this mattress.

Cozy but a little too soft me thinks
It’s very soft and cozy which I love but I’ve had it for a couple weeks and I’m starting to have back issues from not enough support, I guess. I think maybe I need a firmer mattress:/

Onr night - great so far
1st night sleeping on it. So far it met the description. We will see if it holds up to the same new feel. I checked consumer reports before making my next mattress purchase. Paid the same as I did for our previous 3 year old mattress- the sinking Serta. Caused some major pain in my hip.

Great mattress
Mattress is great for normal size people, a little too memory foam for heavier people.
