Product Description

The High-Back Walnut Bentwood Faux Leather Executive Office Chair, model EOB-WB700-CH, features a sleek modern silhouette defined by a smoothly curved walnut veneer bentwood frame that wraps the tall backrest, paired with matte black faux leather upholstery and a polished chrome five-star base for a refined, mid-century-inspired professional look. Its armless, open-side profile creates a streamlined visual footprint that integrates seamlessly with coordinated desk setups without bulky protruding elements. The chair’s frame and supporting structures are engineered for consistent long-term use: the back frame uses 12mm bent plywood finished with walnut veneer, the seat pan rests on 15mm plywood secured with steel mounting brackets, and the 2mm thick chrome-plated steel five-star base uses welded leg construction for stable support. Upholstery consists of 1.2mm thick wear-resistant, waterproof black PU faux leather, fitted over high-density polyurethane foam cushions; the seat core uses 45kg/m³ density foam with 40% rebound, while the backrest uses 40kg/m³ density foam with 45% rebound and 60mm thickness for cushioned support. Moving components include a 50mm diameter Class 3 chrome-finished steel pneumatic gas lift, 3mm thick black powder-coated stamped steel tilt chassis, and 50mm diameter black nylon twin-wheel casters with soft treads designed to avoid marking floor surfaces. For daily functionality, the chair supports 100mm of pneumatic seat height adjustment via a side lever, locking at any point across its travel range, alongside full 360-degree swivel rotation for easy multi-directional access. Its tilt mechanism allows up to 135 degrees of backward recline with adjustable tension control, and includes a lock to secure the chair in an upright position for focused work, plus three suggested lock positions including a 125-degree recline for relaxed postures. The casters roll smoothly across hard floors and low-pile carpet, and the armless design lets the chair tuck fully under standard 720mm height desks to save space when not in use. It supports a maximum user weight of 136kg, with tested component durability including 300,000 gas lift cycles and 40,000 caster rolling cycles. This chair is well suited for executive private offices, paired with 2.4m executive desks, as well as home office workspaces, modern meeting and conference rooms, co-working open offices, and design studio environments, with its neutral walnut and black finish complementing a range of professional and creative interior palettes. For procurement planning, note that each unit ships in two cartons with a packaged gross weight of 23kg, requires 40 minutes of assembly per set, and fits 135 units in a 20GP container at 85% space utilization. The chair’s overall dimensions reach 700 x 690 x 1220mm at maximum seat height, with a 550mm maximum floor-to-seat height, 490mm backrest width and seat depth, and 700mm caster spread diameter for stable footing across flat work surfaces.
