Terry and bamboo on top, a membrane underneath
These covers put a soft layer on the sleeping side: cotton terry or a bamboo-rayon knit, with a waterproof membrane underneath. The sides and the bottom are a plain fabric, which is where the zipper runs.
Terry adds a little loft and absorbs a spill before it reaches the membrane. It also shows lint and wears a little faster in the wash than a plain knit.
Questions
Questions about cotton top encasements
Is a cotton top cover hotter to sleep on?
A terry top feels warmer than a thin knit to some sleepers, because of the loop pile. A bamboo-rayon knit is the thinner of the two.
Can you wash the cotton top covers at Bed Bug Blocker?
Yes, as each maker prints on its label. Most ask for a warm wash and a low or medium dryer, because high heat wears the waterproof membrane.
