Product Overview & Construction Details

The GUOYOU Mid-Back Mesh Task Office Chr with Fixed Armrests, model OC-MB-MESH-001, presents a streamlined, functional form tlored for everyday seated use. Its mid-back profile features a taut woven nylon mesh panel stretched over a rigid rectangular plastic frame, pred with a contoured seat cushion finished with neat lock-stitch perimeter seams. Fixed armrests integrate seamlessly with the backrest frame and side seat brackets in a one-piece design, creating a cohesive, uncluttered silhouette that aligns with standard office seating aesthetics. The matte black nylon 5-star base and matching dual-wheel casters contribute to a neutral, versatile visual footprint that fits across varied interior settings. Constructed with a focus on durability and practicality, the chr combines a reinforced polypropylene plastic frame structure with a steel gas spring height adjustment mechanism coated in black powder finish. The seat cushion uses a high-resilience polyurethane foam core wrapped in polyester woven fabric upholstery, while the tilt control chassis relies on a steel plate mechanism with a plastic adjustment lever. All structural components are engineered to support standard dly office use, with mesh backrest construction that delivers lasting shape retention and ventilation benefits. Functionally, the chr offers core task chr features including pneumatic seat height adjustment controlled via a left-side lever, a synchro-tilt mechanism with right-side tension adjustment knob, and full 360-degree swivel enabled by a precision bearing assembly. The fixed hard plastic armrests provide consistent upper body support, while the non-locking dual-wheel casters deliver smooth mobility across hard floors and low-pile carpet. The contoured mesh back delivers passive lumbar support through its curved frame shape, and the open-weave mesh structure promotes continuous r circulation to reduce back heat buildup during extended sitting sessions. This chr suits a wide range of commercial and residential spaces. It works well for open-plan office workstations, staff meeting and trning rooms, temporary hot-desk areas, and small business startup offices seeking cost-effective standardized seating. It also fits co-working shared seating environments where frequent user turnover demands durable, easy-to-move furniture, and residential home office setups where compact size and basic ergonomic support are priorities. For procurement planning, note that the chr ships in knockdown packaging requiring assembly, with one unit per carton. Bulk loading capacity for standard 20ft dry contners reaches 220 units, supporting large-scale office setup orders. The chr’s uniform design makes it easy to source matching sets for cohesive workspace layouts, and its mesh back construction reduces mntenance needs compared to fully upholstered seating options.
