materials for comfort and durability: The surface of the stair mats is made from density polyester fibers, with a nonslip selfadhesive TPU backing. When barefoot, the mat feels soft and comfortable, and its thickness helps reduce noise from going up and down the stairs, contributing to a quieter, more relaxing home environment. Nonslip and secure: The TPU backing provides nonslip, selfadhesive performance that firmly attaches the mats to the stairs, keeping the carpet stable so you can move up and down with enhanced safety. Precut size and easy : Each stair mat measures 20 x 76 cm, designed to fit most indoor stairs. If your stairs have an unusual shape, you can easily trim the carpet profile with scissors to achieve a proper fit. Simple installation and maintenance: To install, clean and dry the floor first, remove the protective clear plastic cover, place the stair mats on the stairs, and press to secure. Regular cleaning is recommended to prevent excessive dust buildup and to maintain the stickiness of the mat. Practical use scenarios: Homes with children or elderly family members where slip resistance and noise reduction are important for safety and comfort. Apartments or multistory homes with hard surface stairs where quiet, steady footing is beneficial. Stairs with irregular shapes or dimensions, where you need to trim the mat to fit while still providing full coverage.
