ABSTRACT:
A desk chair mat has a substantially planar upper surface suitable for interaction with a chair support structure, a perimeter defining an outer edge of the mat, a lower surface parallel to the upper surface. An array of blunt projections extends downwardly from the lower surface for engagement with a carpet. Each blunt projection has a smooth end surface spaced below the lower surface by a distance sufficient to penetrate into the carpet pile. The array is generally a regular pattern of the blunt projections arranged at an angle with respect to each nearest neighbor to provide resistance to any lateral movement of the mat with respect to the carpet.
