Product Description

The High-Back Ergonomic Mesh Office Task Chair with Adjustable Headrest and Armrests (model ERG-MESH-TASK-001) is an unbranded ergonomic seating solution designed to balance support, durability, and versatile functionality across public and private work environments. It features a clean, professional neutral grey finish, with a contoured high-back structure paired with a streamlined five-star base for a modern, unobtrusive silhouette that blends seamlessly with varied interior design schemes. Built for long-term use, the chair’s backrest uses tensioned nylon-polyester blend breathable mesh stretched over a glass-fiber reinforced nylon composite frame, engineered to resist abrasion across 30000 Martindale cycles. The seat is padded with 80 mm thick, 50 kg/m³ high-density polyurethane foam with a 55% rebound rate, upholstered in durable fabric, and supported by a 2.5 mm stamped steel chassis. Its reinforced nylon composite five-star base is fitted with 60 mm diameter PU-coated swivel casters, connected to a black powder-coated steel gas lift cylinder rated for 100000 adjustment cycles, with a tilt mechanism tested to 300000 recline cycles. Soft molded polyurethane armrest pads mount to height-adjustable injection-molded nylon supports, and a contoured segmented static lumbar zone aligns with the natural spine curve for consistent postural support. The chair delivers full customizable comfort: stepless gas lift adjusts seat height across 100 mm of vertical travel, with a maximum seat height of 565 mm to suit varied desk heights. The headrest offers 100 mm of vertical travel and 60° pivot rotation, while armrests adjust 70 mm vertically and rotate 35° to match individual posture needs. Users can recline 30° from a 90° upright position to a 120° reclined angle, with a single upright lock position and tension adjustment knob to customize resistance, plus full 360° swivel for easy access to surrounding work surfaces. It supports a maximum user weight of 159 kg. This chair is suited for corporate open office workstations for daily 8-hour seated use, compact home office and study spaces, professional conference and meeting rooms, high-traffic co-working shared workspaces, computer gaming and hobby workstations for extended seated sessions, and administrative or reception workstations. For procurement, teams should note each unit ships as one set across two cartons, with a packaged gross weight of 23 kg per set, 40 minute reference assembly time per unit, and a 20GP container load capacity of 135 sets at 85% space utilization. Its neutral aesthetic and durable multi-user design make it a flexible choice for bulk public furniture deployments.
