Wish I could feel the comfort.

I can only taste this item on the fit to crib, design and washable features. All 5 stars. Unfortunately, I'm too big to try and sleep on it to test for comfort. My granddaughter seems to love it, she likes to play in her crib and lay on the mattress when she first visits and she's 2 yrs old. That's a good sign.
