These anti-fatigue mats are extremely comfortable. Made of high density foam, they allow you to work long hours with little stress on your joints and feet. Use them with barber chairs, salon chairs, shampoo stations, or any workstation where employee comfort is needed. The matte black waterproof surface is easy to wipe-clean and sweep, and makes getting ready for your next client a breeze. They are commercial-grade and extremely durable, resisting punctures and tears from dropped equipment and rolling carts, and can also be used under high heels. Crafted with safety in mind, they feature an anti-slip texture as well as edges that taper to the floor to prevent tripping. A large 3' x 5' area allows you to work around a client while staying on the mat, and the depression will fit standard chairs with a round base 24" in diameter.
