Chair leaves lots of depressions in the chair mat. Seems like it's barely working. Not what I expected from a product that was 20% more than other similar products on line.
I recently had bamboo floors installed in the my office and purchased this floor mat so I could still see the floor while protecting it. That is exactly what I got. It is large enough so I can move my chair to reach the file cabinet and easily enter and exit my desk. It also lets the beauty of my new floor show through.
I ordered a chair mat for Low Pile Carpet from another source and it works great. I recently ordered a few more from Staples and we sink into the carpet. It seems that the chair mat is not sturdy/ thick enough to prevent the rolling feet of our office chairs from sinking into the plastic making it difficult to roll.
