The EX-HB-BK-001 is an unbranded high-back executive office chair, designed with a sleek, formal silhouette anchored by a polished aluminum 5-leg base and matching square-tube armrests. Its black faux leather upholstery, finished with a matte, uniform grain and precise top-stitched seams, creates a refined, professional appearance. A fixed padded headrest extends continuously from the contoured backrest, while armrests feature padded tops matching the seat upholstery for cohesive visual flow. The chair’s layout centers on a synchronous tilt mechanism under the seat, with control levers and a tension dial positioned for easy user access, and dual-wheel casters mounted to each base leg for stable mobility. Constructed with a plywood and steel reinforcing frame, the chair supports durable, long-term use. Its seat and backrest are filled with dense polyurethane foam, with the seat cushion featuring high-density molded foam at its core, wrapped in layered padding for contoured comfort. The polished die-cast aluminum base provides robust structural support, paired with a chrome-plated steel gas lift cylinder for height adjustment. Armrests use rigid aluminum framing, and the tilt mechanism is built from powder-coated steel to withstand regular recline use. Dual-wheel PU casters, with black tread and silver hub details, complete the build, offering smooth movement across floor surfaces. Functionally, the chair delivers core executive seating features: pneumatic seat height adjustment controlled by a right-side lever, synchronous tilt that reclines the seat and backrest together with user-adjustable tension, and a tilt lock function to secure the upright position. It offers full 360-degree swivel via a precision bearing, and the fixed padded headrest and stationary armrests provide consistent forearm and neck/head support during extended seated sessions. This chair fits a range of commercial and premium residential spaces. It serves as primary seating for private executive offices and senior manager workstations, and adds a polished, authoritative feel to conference and boardroom head-of-table positions. For modern open-plan offices, it suits senior staff requiring premium ergonomic support, and it works as high-end guest seating in reception or lounge areas of design-focused firms. It also fits premium home office setups seeking commercial-grade durability and executive styling. For procurement planning, the chair ships in a single knock-down carton, with assembly requiring basic tools. Its static load capacity supports standard executive use, and the frame and mechanism carry a common commercial warranty reference for structural components. Procurement teams should confirm exact material grades, gas lift class, foam compression and fire ratings, and abrasion resistance of the upholstery directly with suppliers, as these details are reference s rather than certified specifications. Freight planning can reference the stated net and gross weights, carton volume, and contner loading quantity for logistics coordination, though these are engineering s rather than supplier-measured values.
