The material for the plastic mat is chosen to providing necessary safety and support convenience for occupied rolling office chairs, such materials include vinyl, acrylic and polyethelene and is also chosen based on its thermal and electrical properties. The heating system places the heating elements into the body of the plastic material which is connected to conventional electrical elements outside the plastic mat, such as power source, GFIs, thermostats, and safety shut offs. Other more complicated electronics, such as anti-static mechanism may be included as needed by the environment.
