Abstract
A lifting chair, having a seat which is pivoted upward, being hinged along its front edge to help lift an individual who has trouble rising from an ordinary chair, also has arms which move upward during this pivoting process. Similarly, the seat and arms are moved downward to help the individual sit down. The linkage preferably is a parallelogram type preventing rotation of the arms as they are moved upward and downward along arcuate paths.
