Product Description

The KANAITE High Back Upholstered Swivel Executive Office Chair, model OFH-PU-918-HB, presents a polished two-tone visual profile anchored by a taupe PU leather primary upholstery, accented with dark gray armrest outer panels and a brushed metal V-shaped decorative detail on the backrest. Its tall high-back structure integrates a fixed padded headrest aligned to support the cervical spine, paired with contoured fixed lumbar padding positioned to match the natural curve of the lower spine. Measuring 660 x 720 x 1180 mm overall, the chair offers a 540 mm clear width between armrests, 90 mm finished seat cushion thickness, 70 mm backrest padding thickness, and a 240 mm tall lumbar support zone, delivering balanced visual presence suited to professional settings.
Constructed for durable daily use, the chair’s seat and back cores use high-resilience polyurethane foam, with 45 kg/m³ density in the seat and 35 kg/m³ density in the back, wrapped in smooth PU upholstery with stitched seams on the padded armrest frames. Internal structural elements include a 12 mm thick molded plywood back support frame, 1.5 mm wall thickness chrome-plated polished steel five-star base, Class 3 steel gas lift with 50 mm outer diameter, 2.5 mm thick steel multi-lock tilt chassis, and dual-wheel PU casters with metal bearing hubs. It carries a 21 kg net weight, with a 150 kg maximum static user weight capacity and 120 kg recommended weight for regular daily use.
Functional features support flexible, comfortable seated work: 360-degree full swivel around the central axis, 100 mm of vertical seat height adjustment controlled via a seat-side lever, 12-degree backward back tilt with single position lock, user-adjustable tilt tension knob calibrated to individual user weight, and non-marking dual casters that roll smoothly on hard floors and low-pile carpet. The integrated ergonomic padding supports medium-duration daily use of 6 hours of seated work per day.
This chair fits a range of professional and residential work settings: its formal aesthetic complements executive private offices for leadership and management teams, its professional appearance supports extended seating comfort in conference meeting rooms, its soft upholstered finish pairs with residential decor for dedicated home office spaces, its polished design conveys a professional image in visitor and reception areas, and its smooth swivel function enables easy collaboration at open plan management workstations.
For procurement planning, note that each set ships across two cartons, with a reference packaged gross weight of 23 kg per set, and requires 40 minutes of assembly per unit. Confirm space allocations align with the chair’s overall dimensions and intended use case to ensure appropriate fit for target installation areas.
