产品描述

The GUOYOU OC-MB-BLK-001 Mid-Back Black Upholstered Executive Office Chair presents a sleek, professional silhouette defined by its monochrome black finish and angled fixed armrests, delivering a streamlined aesthetic that aligns with modern workplace design. The mid-height backrest is contoured to support the mid-back and shoulder blade area, paired with a generously padded seat that creates a polished, executive look suitable for both formal and casual work settings. Constructed with durable, smooth faux leather upholstery with a matte finish stretched over molded foam cores, the chair balances comfort and long-term wear resistance. The seat features a high-resilience polyurethane foam core, while the backrest uses shaped foam over a rigid internal support panel for structural stability. The chair sits on a black injection-molded nylon 5-star base with underside reinforcement, fitted with dual-wheel casters with polyurethane treads for smooth mobility. A chrome-plated steel Class 3 pneumatic gas lift and black steel under-seat tilt mechanism form the core of the chair’s adjustable functionality, with rigid ABS/nylon frame armrests topped with upholstered pads bolted directly to the internal seat frame for solid, stationary support. Functionally, the chair offers pneumatic seat height adjustment controlled by a left-side lever, plus a synchronous tilt mechanism with adjustable tension via a right-side rotary knob to match user weight preferences. An upright position lock engages through push/pull operation of the height lever, securing the chair in a vertical working posture. The chair supports full 360-degree swivel rotation, and its fixed angled armrests provide consistent elbow support at a standard desk-aligned height. The dual-wheel casters enable easy movement across standard office carpet and hard flat floors, making the chair highly maneuverable for collaborative work environments. This model is well-suited for a range of commercial and residential spaces. In commercial settings, it fits seamlessly into private executive offices paired with executive desks, open-plan senior staff workstations, 12-person conference and meeting rooms, and executive office reception or visitor areas, where its uniform black finish supports a cohesive, professional brand image. For residential use, it works effectively with home office desks to support dly work sessions, combining ergonomic adjustability with a refined design that complements home workspace decor. For procurement planning, the chair ships in a knocked-down flat-pack configuration with standard assembly tools required for setup. The static weight capacity aligns with standard mid-back executive chair ratings for typical user loads. When sourcing large volumes, buyers should note contner load calculations are based on carton dimensions, and final material specifications including exact foam density grades, steel gauges, and polymer types require direct confirmation from the supplier against bill of materials documentation. Assembly time follows standard industry benchmarks for 5-star office chair models with basic hardware included.
