I got the twin protector for my toddler’s bed. It’s really comfortable and doesn’t make the bed hot. She has a cooling gel mattress and I can still feel the coolness of that through the mattress protector.
The waterproof side is not noisy. No creaks, squeaks, or wrinkled plastic sounds as you turn in bed. The bamboo side is not rough but it provides enough of a grab to prevent the sheets from slipping around.
Even if I wasn’t worried about accidents happening in the night, I still like the protection this provides from sweat.
This is used on an 11” mattress and the sides tuck under nicely. I was worried the deep pockets would affect the fit and allow the top to move around thus affecting the sheets but it’s not the case.
