protective cover

Crib and mattress covers are typically waterproof and hypoallergenic, forming a full encasement that blocks liquids, allergens and bed bugs to protect the sleep surface.

Protectors use zippered encasements, overlap or zip closures, and fitted-sheet styles with elasticized corners. Zippered encasements provide a full barrier, while fitted protectors slide on like a sheet for easier removal and laundering.

Changing pad liners typically have a waterproof, PVC‑free backing that prevents leaks from reaching the pad. Most are machine washable and dryer‑friendly; labels commonly recommend washing before first use and following the machine‑wash and tumble‑dry instructions.

Protective covers commonly use plastics and textiles such as polypropylene, polyester, vinyl, nylon, and blended fabrics (for example 79% nylon/21% polyethylene), chosen for waterproofing, durability and breathability.
