Product Description

This high-back brown executive office chair, model EO-HB-001-LTHR-CGN, features a polished, professional silhouette defined by its tall contoured backrest with an integrated fixed headrest, T-shaped fixed armrests, and a sleek five-star base finished to match its silver-toned metallic frame. All proportions align with premium executive chair industry standards, with balanced dimensions that deliver a substantial, authoritative presence without overwhelming surrounding work surfaces, accented by consistent, high-strength edge stitching along all upholstered surfaces.
Construction combines durable, performance-focused materials across all contact and structural points. Upholstery uses smooth brown 1.2mm polyurethane faux leather, fitted over molded high-density foam cores: the seat uses denser foam to resist long-term sagging, while the backrest uses slightly softer high-resilience foam for targeted lumbar support. The structural frame, armrest supports, and five-star base are crafted from polished die-cast aluminum alloy, paired with a black powder-coated steel tilt chassis, Class 3 steel gas lift, and black polyurethane twin-wheel casters. Armrest pads feature a complementary brown wood-grain finish for cohesive visual flow, while the internal back support uses reinforced multi-layer plywood to prevent warping over extended use.
Functional design supports all-day seated work, with pneumatic seat height adjustment controlled by an under-seat lever that locks at any preferred height across its full travel range. A synchronized tilt mechanism links the seat and backrest for smooth, controlled recline, with an accessible front tension knob to adjust resistance to match user weight, and a lock to hold the fully upright position for focused work. Casters swivel 360 degrees for quiet, mark-free movement across hard flooring and low-pile carpet, while the fixed armrests and angled integrated headrest provide stable support for typing, meetings, and relaxed recline.
This chair is well suited for formal commercial spaces including executive private offices, corporate boardrooms, client reception suites, and open-plan senior work zones, as well as premium residential home offices for senior professionals. It pairs seamlessly with standard-height office desks and conference tables, and accommodates a wide range of adult users for daily 8-hour use.
For procurement planning, the chair ships as a single flat-packed unit with all required hardware for straightforward assembly, with standardized packing dimensions suitable for bulk freight calculations. Buyers should note that material specifications require bill of materials confirmation from suppliers prior to final order placement, and adhere to the stated safe working load for daily use to maximize product service life.
