Rubbermaid® Advantage Chair Mat, Standard Lip, 36" x 48"

These contemporary chair mats for carpet feature ramped edges that facilitate easy roll-on and off while the cleated bottom prevents the chair mat from slipping. 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 task in your workspace. Made of durable clear vinyl to hold up to constant use. Backed by the manufacturer's limited lifetime warranty.
