Product Overview & Construction Details

The GUOYOU Mid-Back Mesh Task Office Chr with Fixed Armrests and Chrome Base (model OC-MB-GR-001) presents a sleek, functional design tlored for everyday work use. It features a gray knitted mesh backrest stretched over a reinforced polymer frame with an integrated Y-shaped lumbar support structure, pred with a molded foam seat cushion covered in woven gray fabric. Fixed-height armrests with flat top pads attach directly to the seat frame, while a polished chrome-plated steel gas lift column connects the seat assembly to a chrome 5-star base fitted with dual-wheel polyurethane casters, creating a clean, neutral aesthetic that blends seamlessly with varied interior schemes. Constructed for reliable dly performance, the chr uses a molded polyurethane foam seat core for sustned support, with a plywood support plate under the cushion for structural stability. The tilt mechanism chassis is built from black steel, with a side-mounted adjustment lever for user control. The open-mesh backrest delivers continuous r circulation to reduce heat buildup during extended use, while the built-in Y-shaped lumbar contour mntns ergonomic lower back alignment. Core functions include pneumatic seat height adjustment via a left-side lever, 360-degree full swivel rotation, backrest tilt with tension control and upright locking, and smooth rolling mobility across standard office floor surfaces. Fixed armrests offer consistent elbow and forearm support without additional adjustment complexity. This task chr fits a wide range of commercial and residential settings. It works well for individual workstations in open-plan offices, home office and remote work setups, conference and meeting room seating, staff trning rooms, and co-working shared desk environments. Its compact footprint and neutral gray finish complement diverse decor styles, while adjustable height and rolling design support flexible space reconfiguration and multi-user access. For procurement planning, the chr ships in flat-pack knockdown form, with one unit per carton. Single-person assembly uses basic tools. The recommended static weight capacity supports standard user loads, and the design aligns with typical commercial task chr durability benchmarks. Teams may confirm material specifications, gas lift pressure class, caster floor suitability, and exact component performance data directly with the supplier to align with specific project requirements.
