This 36" x 48" plastic mat for under office chair shields your low-pile carpet and steadies a rolling seat with a durable anti-skid surface. Featuring ultra-clear vinyl, the mat for under desk chairs guards flooring throughout a long workday, serving office workers and other professionals who want to protect carpet. At 2.2 mm thick, the rolling chair mat for carpet acts as a dependable rug protector, blocking stains, dirt, casters, and heels so floors last longer. Molded cleats and studs keep these chair mats for carpeted floors immobile, while sturdy plastic resists cracking, chipping, or shattering during normal use. Anchor bars secure the piece even on dense carpeting; it is not intended for hard surfaces. The clear protector ships rolled—allow 48–72 hours for it to relax and flatten before use. Not intended for use on hard floors.
