Product Description

The Mid-Back Grey Mesh Ergonomic Office Task Chair with Fixed Armrests, model MTC-MB-GR-066, presents a streamlined, professional silhouette defined by its coordinated light grey palette and functional mid-back form. Its layout centers on a contoured backrest paired with a generously proportioned seat, rigid fixed armrests positioned for consistent forearm support, and a stable five-star base that anchors the swiveling seat structure, creating a balanced visual profile suited to both formal and casual work environments. Constructed for regular daily use, the chair features a breathable woven polyester mesh back set within a light grey PP and nylon frame, with an integrated curved lumbar rib that aligns with the natural lower back curve. The seat uses a thick high-density polyurethane foam core wrapped in wear-resistant grey fabric upholstery, supported by a multi-layer pressed forming board. Its height adjustment relies on a Class 2 steel gas lift connected to a steel swivel-tilt chassis, mounted to a glass-fiber reinforced PP five-star base fitted with PU twin-wheel swivel casters. Fixed PP armrests with integrated top pads are secured to the seat frame to maintain consistent support height. Core functional features include pneumatic seat height adjustment, 360-degree swivel rotation, and a 12-degree backrest tilt with an under-seat tension adjustment knob, plus an upright tilt lock to hold the back in a fixed position for focused work. The dual-wheel casters roll smoothly across hard flooring and low-pile carpet, while the breathable mesh back supports air circulation during extended seating, with construction validated for 8 hours of daily use. This chair fits a wide range of spaces, including open office workstations aligned with standard desk cubicles, home office study areas where its neutral grey finish complements residential decor, meeting and conference rooms, educational computer labs, and reception or admin areas. For procurement planning, note each unit is shipped across two cartons, with a per-set assembly time of 40 minutes, and a maximum static user weight capacity of 136 kg. The chair pairs with standard office desks and larger executive desk formats to support flexible workspace layout planning.
