doormat liner

Doormat inserts are usually made from polyester-based fibers — most commonly listed as 100% PET (polyethylene terephthalate) or 100% polyester.

Many inserts use rubber or anti-skid/non-slip rubber backing to help them grip floors; some listings also note other backing fibers as the backing material.

Inserts are typically rectangular, with a common listing size around 22 x 10 inches (often shown as 10 x 22 or 22 x 10).

Many inserts are sold as insert-only and are designed to fit into a separate doormat tray or base. Listings frequently note that the tray or base is sold separately.

Designs include seasonal and holiday themes (Easter, Christmas), faith-based messages, and novelty or event graphics such as pumpkins, bunnies, and other motifs.
