Mattress Protectors & Encasements: Compare Materials & Coverage

Find the right protection for your mattress

Looking for a fitted waterproof layer, wool cushioning with spill protection, or a six-sided zippered cover? Compare these three Sleep & Beyond options to choose the materials and coverage that suit your bed.

A fitted protector and a full encasement are different designs. A fitted protector sits over the mattress with a skirt; an encasement surrounds the mattress on all six sides and closes with a zipper. Neither should be confused with a topper chosen primarily to change mattress comfort.
