Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest, model ERM-HB-GRY-01, presents a clean task-seating form with a gray mesh back and matching headrest, a light gray polymer frame, fixed T-armrests, and a black gas lift. Its five-star swivel base and twin-wheel casters support easy movement, while the tall backrest creates a structured profile suited to desk-focused settings. The overall dimensions are 660 by 660 by 1290 millimeters, with 540 millimeters of clear width between the armrests. Construction balances breathable support with cushioned contact surfaces. The back uses gray woven mesh tensioned over a contoured, light gray injection-molded polymer frame with integrated side supports. The seat combines a molded foam cushion, 90 millimeters thick, with dark gray woven fabric facing and gray side trim. A light gray curved polymer lumbar pad is fixed at the lower back center, and the headrest features a gray mesh face, light gray polymer surround, and vertical support bracket. Fixed polymer T-arms provide flat arm pads, while the black gas lift and caster assembly visually contrast with the lighter frame. Functionality is centered on adjustable ergonomic task support. A right-side lever controls pneumatic seat-height adjustment with 90 millimeters of travel, and the chair rotates through a full 360-degree swivel. The synchro-tilt mechanism allows recline from 95 to 125 degrees, with a lock position and tension adjustment for personalized movement. The fixed-height lumbar pad directs support through the mesh to the lower back, while the independent curved headrest supports the upper neck and rear head zone. The chair is rated for a recommended user weight of 136 kilograms and has a net weight of 18 kilograms. Its published component ratings include a 500-kilogram static base load, 100,000 gas-lift cycles, 300,000 tilt-mechanism cycles, 100,000 caster rolling cycles, and 100,000 seat-impact cycles. This model fits individual workstations in open offices, home offices, and executive desk areas. It is also appropriate for staff zones and shared computer desks where swivel access, rolling mobility, high-back support, a headrest, and defined user capacity are project requirements. Procurement teams should note that each set ships unbranded in two cartons, with packaged gross weight of 23 kilograms, reference assembly time of 40 minutes per set, and carton dimensions of 850 by 420 by 720 millimeters. Planning should allow 0.26 cubic meter per set; the indicative 20GP loading figure is 135 sets at 85 percent space utilization.
