This memory plastic chair mat is crafted from a special rigid material that can return to its flat state after being folded or bent. It has a similar appearance to glass mats, a lightweight build that can withstand heavy pressure. The frosted top surface resists scuffs and scratches, stays nearly invisible during daily use, keeping its like-new look even after long-term use. Before first use, peel off the protective film covering the bottom of the mat. It comes with 4 glue-free anti-slip stickers that use tight molecular adhesion to create friction, providing strong lateral grip to keep the mat securely in place without shifting during regular use. These stickers can be peeled off without damaging floors, can be reused after washing. This desk floor mat works well on hardwood, tile, ceramic, low-pile carpet surfaces, can be used as an office chair mat, floor protector, computer chair mat, desk pad, pet mat. Available colors: 32.5""53"", 45""53"", 47.2""60"".
