Replacing or repairing floors can be expensive. Protect your investment with a durable Evolve Chair Mat engineered to protect your floor from wear due to the wheels of your office chair rolling back and forth over time. The 39" x 52" Evolve Modern Shape Chair Mats have a 26.2" wide x 9.1" deep tapered front lip. The rounded back corners accommodate the circular footprint of 5-star wheel base chairs, offering more efficient use of the mat surface. Designed with industry leading clarity, Evolve mats seamlessly fade into your floors, perfect for low pile carpet floor surfaces including berber, loop, sisal, velour, and carpet tiles. Not recommended for use on hard floors, area rugs, throw rugs, or medium to high pile carpets. Evolve chair mats are backed by a 1 year warranty that guarantees the chair mat is free from manufacturer defects, limited to replacement of the mat only and excludes special or consequential damages.
