Washable and reusable, easy to care for: The mats are soft and stain-resistant, allowing for daily cleaning with a vacuum cleaner or tumble dryer. If they get dirty, they can be machine washed, retaining their stickiness and allowing for repeated use. They're a great value for money. Anti-slip and stable, protecting your family: The elegant diamond-patterned surface provides strong grip and effective anti-slip protection, making it safer for elderly people, children, and pets to climb stairs. The polyester fiber material is also comfortable to the feet. Easy installation and customizable: Clean and dry the stairs first, then remove the backing film and press firmly to install. Be careful not to damage the adhesive when removing. The size fits most staircases, and if they're smaller, you can trim them to your own shape.
