For a standard one-sided protector, strip your bed and place the protector on your bare mattress. Secure each corner pocket around the mattress, much like you’d do with a fitted sheet, until the protector is firmly in place. If you have an encasement protector, first unzip it and then lift your mattress, placing the bottom half around the mattress base. Most mattresses are heavy, so we recommend putting on an encasement protector with a partner.
