Truly the Perfect Sleeper!

Perfect amount of firmness and comfort; definitely helped with healing my total hip replacement.

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.
