Disappointing

Already showing body imprints. Not really "cool" sleeping. It's just ok.

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.
