Anti-Fatigue Office Mat is designed to use with office sit-stand workstations to help reduce leg fatigue while standing. Antimicrobial, PVC foam bottom provides long-lasting performance and comfort. Berber-style, polypropylene surface captures debris and moisture from shoes. Ergonomic design provides extra support with anti-slip surface that prevents the mat from moving. Gently beveled edges allow chair casters to roll over the edge easily. Indoor, light-duty construction is the ideal size for any work space.
