Everything I own that is bamboo is worth every penny. I was looking for a light protective cover for my bed. My cat was peeing (she was sick) on my down comforter, and the 2nd time the pee leaked almost through my pillow top mattress topper. Thankfully it didn't hit the matress. But at that point, I thought "okay I guess that's my sign that I need to protect my expensive mattress".
So I started doing research. I wanted something waterproof (obviously), breathable, durable, doesn't feel like plastic, not too hot, and doesn't get in the way of the pillow topper.
This hit all of those things. While I was putting it on the bed I couldn't help but test it with water.
Poured a little bit on it, good to go.
This works great for what I wanted: optimal protection, comfortibility for a piece of mind and "just in case".
