Abstract
The present invention provides an adjustable furnishing such as a lift chair including a support member with a surface for supporting a user. A mechanism is connected to the support member for adjusting a position of the support member. One or more infrared radiation sensors are positioned beneath the surface of the support member to generate a signal when a heated body is detected in proximity to the mechanism. A controller is provided for receiving the signal from the infrared radiation sensors and inhibiting travel of the mechanism and the support member in a direction of the detected heated body.
