I purchased this because it was on sale and inexpensive.I have it in my living room at my computer desk. I have Persian carpet down and it very quickly left deep indents under the wheels.The mat would be fine on hard floors but I do not recomend ton use it on deep pile carpet.
When we seen what our office chairs did to the old office flooring I ask that these chair matts be used so all we need to replace over time are the chair matts not a whole new floor. Which never happens in the old office.
