MY CHAIR LEAVES HOLES OR RIPPLES IN THE MAT AND MY CHAIR IS JUST A REGULAR OFFICE CHAIR WITH WHEELS AND I ONLY WEIGH 180 LBS. THE HOLES OR RIPPLES GO AWAY WHEN I MOVE THE CHAIR RIGHT NOW BUT WHO KNOWS WHAT MAY HAPPEN AFTER A MONTH OR TWO. THE HOLES THE CHAIR MAKES IN THE MAT MAKE IT VERY HARD TO MOVE THE CHAIR AROUND BEHIND THE DESK. IF YOU BUY ONE YOU WILL UNDERSTAND WHAT I'M TALKING ABOUT BUT REMEMBER I WARNED YOU.....
This is an attractive product and certainly not the least expensive. The thickness and hardness are severely lacking as the chair wheels dig into the surface as well as create potholes that are difficult to get out of. I am constantly realigning it as it slips all over the carpet. Not recommended at all over carpet.
