I got this for my office that we converted from a bedroom. So it has carpeted floors. Not wanting to ruin the carpet I purchased this chair mat. Well it's so thin the wheels of the chair creates divots so deep the chair doesn't roll freely. I should have purchased a mat that's thicker. So don't make the same mistake I did.
MY husband decided he wanted a chair mat because I have been using one for a number of years and his chair is on a rug and just thought it would be easier for him to maneuver around. He loves it as I do too although mine is on a floor.
This replaces an old carpet chair mat from Staples that lasted over 5 years before it started to get cracks and a hole (with constant use). Hopefully this one will too; it seems to be about the same weight and thickness as the old one.
