Claim:
A heated seat comprising: a. a cushion and/or back with one or more trench areas; b. a heater comprising: i. a carrier with a periphery, the carrier further including: 1. a first electrically functional layer that is made of a conductive material that substantially circumscribes at least a portion of the carrier; and 2. a second electrically functional layer that is made of a resistive material; 3. one or more electrical conductors, which supply power to the heater, attached to the first electrically functional layer; c. a trim layer that covers the cushion when the heater is placed over the cushion; and wherein the periphery includes a first side edge and a second side edge, and each side edge includes a cutout, and the cutouts are located adjacent to each other forming a neck portion; wherein the heater is attached to the cushion by placing an attachment device over the neck portion of the heater and securing one or both ends of the attachment device to the cushion so that the neck portion is pulled into the trench; wherein the neck portion is free of the second electrically functional layer; and wherein the second electrically functional layer forms a checkered pattern with alternating resistive areas and gaps as the second electrically functional layer extends along a width of the heater.
