The Glammar Anti-Fatigue Mat Round Black Small is made with extra-flex foam in combination with a performance rated polymeric surface that resembles the natural springiness of walking on a manicured lawn, reducing the impact of strain to your feet and legs providing a natural form of support on long days of standing. The Anti-Fatigue Mat springs back after pressure has been removed from an area that had been used. The 1” thickness of the Glammar mat is double the thickness of ordinary mats and is static free ensuring ease of cleaning.
