Office Depot(R) Economy Chair Mats

These chair mats offer a great value while protecting your floors. Designed to prevent chair wheels from ripping the carpet, these mats feature a cleated bottom to prevent the chair mat from slipping. The smooth surface of the mat helps reduce friction caused by rolling your chair from your computer to your filing cabinet or bookcase, thereby reducing strain on your back, legs and arms. Chair mats help reduce repetitive strain injury and lower back fatigue that could occur when rolling your chair manually. They also help increase productivity as you can roll from task to in your workspace. Clear mats are made of tough vinyl and work well on industrial-grade carpet up to 1/4in. thick.
