Firm but comfy

It’s a really nice mattress we just have to get use to the firmness!

Mattress is very pretty in color and comfortable. I hope it will last at least 10 years.

Truly the Perfect Sleeper!

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