Waterproof Mattress Protectors
A mattress protector is a fitted cover that goes on the mattress under your sheets and keeps spills, stains and moisture from soaking in. Superior® carries two. One has a soft cotton terry top over a waterproof microfiber base and fits mattresses up to 22 inches deep. The other is made with rayon from bamboo, uses a quiet vinyl-free waterproof backing and fits mattresses up to 18 inches deep. Both go on like a fitted sheet and come off for washing.

- Waterproof Mattress Protector Cover — the best-selling protector, a cotton terry top over a waterproof microfiber base, sized for mattresses up to 22 inches deep.
How to Choose a Mattress Protector
Measure the depth of your mattress first, including any pillow top. The terry protector fits up to 22 inches and the rayon from bamboo protector up to 18 inches. If the protector is too shallow it will pull off the corners.
Then pick the surface. Cotton terry is absorbent and soft, with a slightly thicker feel. Rayon from bamboo is lighter and smoother, and its vinyl-free backing keeps it quiet when you move.
A protector is not a comfort layer. If you want a softer bed, put a mattress topper on first and the protector over it, then your fitted sheet set on top.
