The clear chair mat does the job for my vinyl floor appears to be well made and doesn't slip. Fits well with my desk. Delivered promptly and wasn't curled so I didn't need to flatten it. So far so good.
Great for my L shaped desk area. I have a small armless chair on wheels and the chair mat fits in the L so I can roll easily in my chair. I bought the wrong one initially but the staff at staples was very helpful in helping me get the correct one.
