Product Description

The Ergonomic High-Back Mesh Office Chair with Adjustable Headrest and Lumbar Support, model ERG-OFC-MSH-001, is an unbranded public and workspace seating solution designed for long-duration seated use. Its streamlined, contemporary form features a contoured high-back profile paired with a wide, supportive seat, structured to deliver consistent postural alignment without bulky, obstructive detailing. The open mesh back creates a light, unobtrusive visual presence suitable for a range of interior design schemes, while the polished five-star base adds a refined, durable structural anchor. The chair is constructed for long-term heavy use, with a tensioned breathable polyester mesh backrest supported by a glass-fiber reinforced polypropylene internal frame. The seat uses a high-resilience molded polyurethane foam core with 90mm cushion thickness, topped with breathable mesh upholstery. Other structural components include soft-touch polyurethane armrest pads on plastic supports, a polished die-cast aluminum alloy five-star base, 60mm diameter polyurethane dual-wheel casters, and a chrome-plated steel Class 3 gas lift paired with a 2.5mm thick stamped steel multi-lock tilting chassis. The mesh fabric withstands 50000 double rubs for abrasion resistance, the casters deliver 40000 cycles of rolling durability, and the gas lift supports 120000 adjustment cycles, with a maximum recommended user weight capacity of 150kg and net weight of 22kg. Functional design supports personalized, comfortable positioning across varied user needs: seat height adjusts 100mm vertically with lockable positioning at any point in range, the headrest offers 40mm of height adjustment and 30-degree tilt to support the cervical spine, armrests adjust 75mm in height to align with different desk surfaces, and the backrest offers 22 degrees of synchronized tilt with a 3-position lock and adjustable tension control. An elastic self-adapting lumbar panel flexes with natural back movement to maintain consistent lower back support, while 360-degree swivel seat movement and dual casters enable smooth, multi-directional access across hard floors and low-pile carpet. This chair is well suited for corporate open office workstations supporting 8-hour daily desk tasks, home office study spaces paired with standard 760mm height office desks, executive private offices for management roles, conference meeting rooms for long collaborative sessions, and IT or coding workstations where extended screen time requires flexible posture support; it is recommended for pairing with a 2.4m executive desk for optimal fit. Procurement teams should note each unit ships in 2 cartons, with a packaged gross weight of 23kg per set, 0.26m³ carton volume, and 40 minutes of required assembly time per unit; a 20GP container can hold 135 sets at 85% space utilization for bulk order planning.
