Abstract
A chair comprises a seat, legs for supporting the seat, a backrest frame connected to the legs, and a backrest attached to the backrest frame. The backrest includes a backrest panel and backrest inserts. The backrest panel has slots extending inwardly from peripheral edges of the backrest panel. Each insert is configured for sliding insertion into a corresponding one of the backrest slots. The backrest is secured to the backrest frame by fasteners that pass through the backrest frame and into a corresponding one of the backrest inserts. The backrest inserts may be formed of a sturdy plastic to provide a secure anchor point for the fasteners. This provides a significant advantage for chairs having backrest panels constructed from relatively soft materials, such as pressed wood fiberboard. With the fasteners driven into the inserts, rather than directly into the soft backrest panel, any pulling or shearing loads on the fasteners are transferred to the interface between the inserts and the slots in the backrest panel.
