Abstract

A synchrotilt chair includes a base, a back, a seat, and a link(s) pivoted to a rear of the base and to a bottom of the back to form a four-bar linkage arrangement. A spring arrangement includes a resilient member at one of the joints of each link to bias the link and in turn the back and seat toward an upright position, with the back and seat pivoting with a synchronous motion upon recline of the back. In one form, the chairs are nestable and stackable for dense storage. In another form, the chairs are desk-type pedestal chairs. Several of the structural support members of the chair are gas-assisted injection molding to form a hollow tubular shape that is lightweight, strong, and dimensionally-accurate. Armrests are pivoted to the back and have a shape configured to allow nested stacking while also providing excellent comfort, durability, and style. Also, the armrests are movable to remote storage positions to provide unobstructed side access to the seat of the chair.
