Stand for long periods of time in comfort using this Anti-Fatigue Mat. This Pthalate-free non-toxic padded mat measures 36" x 24" (915 x 610 mm) and weighs only 4.5 lbs (2.1kg). Its 3/4" (20mm) thickness is comfortably soft eliminating the muscle and joint pain that comes from standing on a hard unpadded surface such as concrete. The textured surface prevents slipping and the angled sides prevent it from being a tripping hazard.
