ABSTRACT:
A structure for assembling chair bases by cladding the chair bases with wood grain finish strips is provided. The chair bases have notched slots formed at appropriate placed on both sides of each plastic strut foot. A scoop channel is formed in the strut foot surface near the central pivot joint of the base. A drilled hole is located inside the scoop channel. A connecting hole is formed in the outer bottom edge of each strut foot for attaching a wheel set thereto. There is a wood grain finish strip for each strut foot. Each strut foot has an inverted U-shaped cross-sectional contour and pintle hooks located in correspondence with the notched slots on both sides of each strut foot. The outer bottom edge of each wood grain finish strip extends inwardly to form a flange of suitable length to extend over the outside of the strut foot.
