Story
Frame and finishes
The shop gives the frame as welded steel rods in a bonded Rilsan, polished chrome or 18K gold-plated finish, and the design page's finish tab lists eight frame entries: Chrome, Polished; Chrome, Satin; Gold, 18k Plated; Black; White; and a Two-Tone Frame in Blue or Red. Wikipedia describes Rilsan as an adhesive-fused, nylon-dipped finish that resists scratches, chips and chemicals.

Seat pad or full cover
Wikipedia says cushions are secured to the chair with lock snaps and full covers are stretched over the wire seat basket and hooked to it. Knoll's shop page lists the seat pad as secured with metal snaps and offers a full cover or a foam seat pad. The design page names a vinyl seat pad as suitable for outdoor use, and the shop names a Chain Link seat pad in solution-dyed olefin.
