Abstract

A boat captain's helm chair has a seat part which is movable forwardly and rearwardly relative to a support, and a backrest with a retaining member such that its forward movement is counteracted. The forward portion of the seat part is rounded relative to the remaining portion to provide a support for the user in both a sitting and semi-standing rearward leaning postural position. Side portions of the seat extend forwardly of its mid portion to prevent lateral movements of the user. A compressive distortion of the armrest is counteracted by a dense U-shaped shock absorber to prevent the distortion of the armrest from constant use.
