Need help? Take a look at our helpful article on how to select the right chair mat and properly measure for it.
The Beveled Edge:
A beveled edge greatly reduces the potential tripping hazard of a chair mat. It is also very useful if you need to transition on or off of the mat. Add this feature for just $10.
Moisture Control Feature:
Chair mats create the ideal surface to roll on but in humid conditions or when a mat is placed on a carpeted area where the concrete was not properly sealed, serious issues can arise. The moisture under the mat is trapped so it accumulates under the mat until mold or mildew starts to grow. This creates a very unhealthy condition. The Moisture Control Feature provides holes every 2 inches to allow moisture to escape! They are made by hand in our state of the art production facility and are perfect for basement offices or other high-humidity environments.
