产品描述

The GUOYOU Mid-Back Black Upholstered Swivel Office Chair, model OC-MB-BK-001, is a functional office task chair defined by its clean, streamlined silhouette and space-efficient mid-back form. Its all-black aesthetic features smooth, matte-sheen faux leather upholstery with neatly stitched edges, paired with a rigid matte black 5-star base and fixed rectangular armrests, creating a professional, understated look that integrates seamlessly with varied interior schemes. The chair’s balanced proportions support unobtrusive placement in both open and compact work layouts. Constructed with a black PVC/PU blend faux leather upholstery covering dense polyurethane foam seat padding and a molded foam backrest built over a multi-ply plywood inner frame, the chair delivers firm, supportive seating. Its fixed armrests feature reinforced nylon support brackets topped with hard PU pads, mounted securely to the seat frame. The height-adjustment system uses a steel gas lift cylinder with a black outer sleeve, while the 5-star base is made of powder-coated cold-rolled steel for structural stability. A stamped steel plate tilt mechanism with tension adjustment spring sits under the seat, and twin-wheel nylon/PU casters with metal axles attach to each base leg. Bonded polyester thread forms uniform seams across the upholstered surfaces. Practically, the chair offers pneumatic seat height adjustment via a right-side lever, with full 360-degree continuous rotation supported by a steel ball-bearing race. It features synchronous seat and backrest tilt up to 15 degrees, with three lockable positions and a rotary tension knob under the front of the seat to adjust recline resistance to user weight. The fixed armrests provide stable forearm support, and the five twin-wheel casters enable smooth maneuvering across hard floors and low-pile carpets. The 5-point symmetrical base distributes the maximum recommended user load evenly to prevent tipping. This chair is suited for a range of commercial and residential spaces. It works well for individual corporate workstations in both open-plan and closed offices, where its mid-back design balances lumbar support with sle space efficiency. It fits formal meeting and conference room settings, and serves administrative and front-desk positions that involve long periods of seated work and frequent movement. For shared environments such as co-working spaces with hot-desking, its durable adjustable components and easy-to-clean surface support multi-user use. It also integrates into home office setups, pring with standard desk heights for personal work use. For procurement planning, the chair ships flat-packed in knock-down form for single-unit assembly. Each carton holds one chair, with a gross weight of 20 kg and a carton volume of 0.126 cubic meters. A 20-foot contner holds 260 units. Assembly takes 30 minutes per unit with basic tools. Note that exact material specifications, component grades, and certification details require confirmation from the supplier, as listed values are reference s based on comparable category product standards.
