Product Description

The Grey Mesh Ergonomic Task Chair with Lumbar Cushion and Height-Adjustable Arms is a practical seating solution for desk-based work, presented in a neutral grey finish that blends easily with modern interiors. Its visual character is defined by a woven flexible mesh backrest tensioned over a light grey polymer perimeter frame, matched with a mesh seat surface over a molded ergonomic carrier. A separate curved mesh lumbar panel sits within the lower-back area, while light grey polymer arm caps and vertical posts complement the frame. The black steel synchro-tilt mechanism, black gas lift, and five-star base provide a structured contrast beneath the seat, giving the chair a functional, contemporary appearance. The chair is built around breathable mesh upholstery and polymer support components, with steel adjustment inserts in the arm assemblies and a black steel synchro-tilt mechanism below the seat. The seat cushion has a finished thickness of 90 mm, and the backrest padding is 70 mm thick. The lumbar support zone is 240 mm high, while the clear width between the armrests is 540 mm. Its light grey five-star base is available in polymer or painted-metal construction, paired with twin-wheel casters and a black 50 mm Class 4 gas lift. Functional adjustment is centered on regular workstation comfort. A pneumatic lever raises the seat from 440 to 540 mm through a 100 mm Class 4 lift travel, and the height-adjustable arms allow users to tailor support relative to the desk. The synchro-tilt mechanism enables the back to recline to 118 degrees, with multi-position lock and return tension control. The seat also offers a tilt range up to 118 degrees, a 360-degree swivel, and five dual-wheel casters for easy movement around a workspace. The framed mesh lumbar cushion is positioned by a rear bracket and shaped to follow the lower back. This model is suited to individual office workstations, shared desks, meeting spaces, home offices, study rooms, and flexible task seating where a neutral caster-based chair is required. The breathable mesh, adjustable arms, lumbar support, and swivel mobility are intended for seating tasks lasting 6 to 8 hours. The listed recommended user weight capacity is 136 kg, and the chair has a net weight reference of 17 kg. Procurement planning should account for the supplied model identifier ET-MESH-GY-01 and its unbranded status. Each set is supplied as one chair across two cartons, with a packaged gross weight of 23 kg and a reference carton volume of 0.26 m³ per set. Reference assembly time is 40 minutes per set, making on-site assembly and staffing time important considerations for multi-unit projects. Buyers should also confirm the required base material when ordering and review the listed mechanism, gas-lift, caster, and backrest test targets against internal purchasing requirements.
