Can I use an office chair on a thick area rug without a chair mat?

Area rug placement under office chairs is an accessibility and stability concern we address during office planning consultations. The solution is a heavy-duty 3/16\" polycarbonate chair mat placed over the rug surface — this bridges the pile and provides a stable, smooth caster surface. For rugs with particularly deep pile (over 3/4 inch), double-sided mat underlay may be required to prevent the mat from migrating. We specify mat dimensions to extend 24 inches beyond the full chair movement range. Call 1-800-460-0858.
