They imprinted the marks from the chair within the first week on the floor. The chair doesn’t even roll around on them hardly anymore because it gets stuck in the holes they’re so deep. You would think I weighed 300 pounds. There a ridiculous waste of money. Way too thin for their use intended.
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.
