Firm and comfortable

Love new mattress. Side sleeper and it is not too firm to cause discomfort. Highly recommend.

Getting to know each other

First few nights was a little stiff. But now settling in and super comfortable.

So so

Seems to stay indented where I sleep. Didn’t think I would have that with such an expensive mattress. But seems to be comfortable.
