This upgraded Pvc chair mat lays flat naturally to eliminate curled edges and protect your floors. If edges curl slightly after unboxing, simply weight them down, they will flatten fully within a day, faster than stiff plastic mats.

The textured rubber backing provides a secure, firm grip without industrial glue for stable, odor-safe use.

Its durable woven surface resists scratches, spills, burns, repels dust with a static-resistant finish, is safe for heated floors. Optimized for Pu and nylon casters, it rolls smoothly and wipes clean easily. Available sizes: 35"" x 47"", 45"" x 53"". Available colors: Black+white, Brown, Dark Brown, Gray Diamond.
