I was first pleased with the price of this Staples chair mat and that it was in stock at the store. Next I have to say I was pleased that the weight of it. It had a curl to it from the ride home in the car. An hour or so I returned to my office to see it was laying completely flat.
Purchased tis mat about 3 weeks ago. Says its for medium pile carpeting not at all accurate. After about 3-4 days of use the chair wheels started making impressions into the mat. Will be returning as soon as possible.
This chair mat is the only one that I found that is thick enough that works on thick carpet and holds the chair so it doesn't sink into it rendering is useless. Great buy and great product.
