ABSTRACT:
A heating system has been incorporated into the commercial space fixture of a plastic chair mat to provide a space-saving heating system. The material for the plastic mat is chosen based on its thermal and electrical properties to provide necessary safety and support convenience for occupied rolling office chairs. Materials include vinyl, acrylic, and polyethylene. The heating elements are placed into the body of the plastic material, which is connected to conventional electrical elements, such as power source, GFIs, thermostats, and safety shut offs, outside the plastic mat. Other more complicated electronics, such as an anti-static mechanism, may be included as needed by the environment.
