What chair mat should I use under an executive chair?

For carpeted floors, choose a polycarbonate chair mat with carpet grippers (nubs) on the underside, sized at least 36"x48" to cover rolling range. For hard floors (wood, tile, LVP), use a smooth underside mat or switch to hard-floor casters. Polycarbonate mats are significantly more durable than PVC mats and don't crack in cold climates. For executive office aesthetics, tempered glass mats are available at a premium. OfficeFurniture2go.com can recommend appropriate floor protection for your setting — call 1-800-460-0858.
