Product Description

This high-back bentwood padded executive swivel office chair balances refined modern styling with commercial-grade functionality for diverse work settings. Its visual profile centers on a smoothly curved bent laminated plywood shell finished with natural zebra wood grain veneer and a clear matte lacquer, paired with uniform black matte upholstery across the seat, contoured backrest, fixed curved armrests, and integrated headrest. All bentwood edges feature smooth rounded treatment to eliminate sharp contact points, while a polished chrome-plated 5-star tubular steel base and black nylon twin-wheel casters create a clean, professional visual contrast suited to coordinated workspaces. The integrated fixed headrest rises to the full tall back height, delivering a streamlined silhouette without protruding adjustment components. Construction pairs the 15mm thick bent plywood outer shell with tailored padding: the seat uses 80mm thick high-density polyurethane foam, while the backrest uses 60mm thick medium-density foam, with upholstery stitched at a commercial-grade density to resist seam failure. The base connects via a Class 3 commercial-grade chrome-plated steel gas lift cylinder, paired with a steel tilt chassis and hard-floor casters fitted with metal roller bearings for smooth movement. Functional features include 360-degree continuous swivel, 100mm of vertical seat height adjustment, a 12-degree synchronized backrest tilt with user-adjustable tension and upright lock, passive lumbar support from the contoured shell shape, and fixed padded armrests positioned to support forearms during desk work. The casters roll smoothly on hard tile, wood, polished concrete, and low-pile carpet surfaces without causing scuff damage. This chair is well suited for executive private offices, senior staff open-plan workstations, formal boardrooms and meeting spaces, premium co-working dedicated desk zones, and upscale residential home offices. Its neutral black and wood finish coordinates with most modern fitout palettes, and its commercial-grade build supports frequent daily use across high-traffic and private settings. For procurement, note that the chair ships as one unit per carton, with assembly time of 20 minutes for a single person to attach the base, casters, and complete a post-assembly inspection. The product carries a 3-year standard warranty for commercial use, with a maximum static user weight capacity aligned to commercial office seating standards. Buyers should confirm exact upholstery material (fabric or PU leather) and final material grade specifications via supplier bill of materials prior to bulk order placement, and account for standard container loading quantities when planning large-scale installations.
