When selecting a non-slip bathroom mat for the elderly, several factors should be considered. First, the mat should have a strong, anti-slip backing that can adhere securely to the bathroom floor. This feature prevents the mat itself from sliding around, ensuring it remains in place even when pressure is applied. Second, the material of the mat should be both durable and comfortable. Look for mats made from high-quality rubber or microfiber, which can withstand frequent use while providing a soft feel underfoot.
