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 generally blunt projections extends downwardly from a first area of the lower surface for engagement with a carpet. An image is formed within a second area of the lower surface. 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 projections that can be arranged at an angle with respect to each nearest neighbor to provide enhanced resistance to lateral movement of the mat with respect to the carpet to protect the image from abrasion.
