New type chairmat

A chairmat having a gripping surface formed from a plurality of interlocking ridges extending from the bottom of the mat is disclosed. Each of the interlocking ridges may be configured so as to form a plurality of interlocking shapes, such as hexagons, rectangles, other polygons, or arcuate shapes. In so doing, not only is the mat provided with a mechanism by which the underlying surface can be gripped, but also is provided in a form which prevents the formation of any sharp edges on the bottom of the mat which would otherwise be negatively viewed by consumers and sales personnel.
