the mat is probably fine for berber or short-hair carpet. I had it for thick carpet and it is not working well. It keeps moving and I need to adjust it daily
The material is too soft and the chair wheels make indentation ruts that are hard to move out of...I'd buy the Polycarbonate version but it's almost three times as much...
If you join Staples Rewards you will get great emails offering numerous valuable coupons. I could have chosen any office supply store to purchase my carpet chair mat but there it was a COUPON just for Reward members and I got $10.00 of the purchase of the carpet chair mat. I probably would have waited a longer amount of time and just suffered with the old carpet chair mat that was cracked; the coupon was the catalyst that prompted the purchase and at Staples. The sales people at the store are always very helpful.
