ABSTRACT:
A rocking chair of the type employing a flexure member formed of a flat, fiber reinforced material for supporting a chair seat with respect to a chair base in which the support means for supporting the flexible sheet member from the chair base has a flat surface to which the sheet member is secured and an aperture above the flat surface through which the sheet member extends, the opposed walls of the aperture diverging from top to bottom to allow flexing of the sheet member with the effective length of the flexure member decreasing as the chair is rocked rearwardly. The sheet member is preferably disposed at an angle to the vertical of between five and fifteen degrees, to impart an initial bias on the sheet member. The rear wall of the aperture is curved to allow a greater length of the sheet member to flex as the chair is rocked rearwardly.
