Listings commonly show dimensions such as 24 x 38 inches (often with a 5 in. pocket) and smaller bassinet sizes around 32 x 16 inches.
Many listings specify a maximum mattress depth of about 5 inches for a snug fit.
Many sheets use elasticized edges—examples include fully elastic bottoms, reinforced elastic bands, or strong elastic edges—to help hold the fitted sheet securely in place.
Some listings include a waterproof option with a TPU (thermoplastic polyurethane) lining that serves as a built-in mattress protector.
The listings commonly recommend machine wash and tumble dry.
These listings commonly offer either single sheets or two-packs.
