I had high hopes for this mattress, given the Wirecutter reviews, but it ended up with a divot pretty quickly. Haven't attempted to try to use the warranty because I just don't have time for a project like returning a mattress and finding another one. It's not the worst I've ever slept on, but definitely not the best.

Love it!

I will return the mattress as soon as eligible to do so. It is not very comfortable so there is no point in my keeping it. Fortunately I still have my old mattress and will return it to my bed as soon as possible.

Returned after suffering a month of stuff nose and allergies from offgassing. The returns and pick up has been super slow. Suffering from sinus congestion while waiting for this mattress to be taken as far away as possible. Slow response from team despite this being a health issue

Comfort and quality as expected. As far as 'cooling,' don't expect too much. Generally satisfied.
