We had carpet squares put in our new offices abd my chair stuck to one spot like velcro. It flipped me sideways and I hiy my head on the metal table going down. With this new chairmat I feel safe and have no more problems with my wheels getting stopped by the carpet and I won't have to go take riding lessons to keep from getting thrown under my desk by an unruly chair with an attitude. I think everyone who has a chair that has qualified foir the rodeo ought to get one or two for their desk area and a spare just in case.
This is the second time I've purchased this mat and I will purchase again when needed. All of these mats crack over time but this one holds up longer than the more expensive models and the financial savings is appreciated. The size is perfect and it does not move one bit on the low pile carpet in the office. I would certainly recommend it!
