crib mattress liner

Most crib liners and protectors are made from polyester or polyester blends. Common examples in listings include 100% polyester tops or batting and cotton/poly blends such as 60% cotton/40% polyester.

Most listings target standard crib/toddler mattresses. Typical dimensions shown are about 52 inches long by 28 inches wide, with some options listed near 50" × 27" for standard crib sizes.

Common attachment methods include hook-and-loop adjustments for mesh liners, fitted skirts or full elastic skirts that wrap under the mattress, all-around elastic edges, and zip closures for full encasements.

Product listings typically show compatibility with a range of mattress depths — commonly up to 6 inches, 8 inches, 10 inches, or 12 inches depending on the model.

Common protective features include a waterproof backing or barrier, stain-release or stain-repellent treatments, and full encasements or covers described as blocking bed bugs and helping reduce household allergens.

Care instructions most often list machine wash and tumble dry; product descriptions commonly use phrases like “machine washable” and “dryer friendly.” Follow the item’s care label for best results.

Materials shown in listings include polyester (e.g., 100% polyester tops and polyester batting), cotton/poly blends (such as 60% cotton/40% polyester), and knitted, woven, or plain-weave fabric constructions. Thickness or construction measures in listings include 3 mm mesh and pad thicknesses listed as 0.12 inches, 0.2 inches, and 0.5 inches.

Breathable mesh liners are single-layer mesh constructions that allow air (and exhaled air) to pass through and are described as helping keep limbs inside the crib. Waterproof pads typically have quilted or knit tops combined with a waterproof backing or barrier and may include stain-protection or stain-release finishes.

Listings are commonly sold as single items (package quantity = 1) or as multi-packs such as 2-packs, depending on the product.
