Chair mats are an essential component when furnishing your work or home office. Purchasing a chair mat is a worthwhile investment for assurance that your floors will be protected and are ergonomically beneficial in preventing leg fatigue. Not only do they protect your floors, chair mats offer personal safety with ease of mobility and provide a clean appearance. Our Big and Tall chair mats are an invaluable choice for multi-shift work locations and are rated to hold up to 400 pounds. This carpet chairmat features a scuff and slip resistant textured top and small studded anchors on back to properly grip carpet. This mat includes a protruding lip to protect the floor under the desk when the chair is rolled all the way under the desk.
