It's good. My chair is about 7 years old. Maybe it's heavy because there's already a depression in the mat where the wheels are. Still keeping the mat. Glad there's a one year warranty on the mat though.
Love the fact that I don't have to lift desk to get underneath. Good rectangular shape. Problem was with the sticker. Left a terrible sticky residue that was not easy to remove.
I had gone to the store in person to shop for mats and couldn't find what I needed then decided to shop online and found exactly what I wanted. Easy from start to finish. Thank you!
