Product Description

The High-Back Blue Mesh Ergonomic Office Chair with Headrest, model EMH-BM-01, presents a professional task-seating solution with a blue breathable mesh back, matching mesh headrest, and black structural components. Its visual character is defined by the tensioned blue woven backrest set within a black polymer outer frame, blue mesh-faced seat cushion, black molded armrests, and black five-star base. The high-back form includes a 240 mm lumbar support zone, padded headrest, and 540 mm clear width between armrests, giving the chair a structured appearance suited to focused desk work while maintaining an open, breathable back profile. Overall dimensions are 680 x 680 x 1290 mm. Construction combines upholstered comfort with durable support elements. The seat uses a blue mesh-faced cushion over contoured molded foam and a load-bearing seat shell. The finished cushion is 90 mm thick, with 45 kg/m3 molded high-resilience foam and 42 percent rebound. Backrest padding is 70 mm thick, and the fabric mesh is selected to a 50,000 Martindale-cycle abrasion acceptance target. Black molded T-polyurethane arm pads sit on black steel or die-cast support posts, while the multi-position tilt mechanism uses a black steel top plate and tension-control housing. A black 50 mm outer-column gas lift connects the mechanism to the nylon five-star mobile base fitted with twin-wheel casters. Functional adjustment is designed for personalized seated support. A side lever beneath the right seat operates the pneumatic height adjustment, raising seat height from 450 to 540 mm. The synchro-tilt mechanism moves the back and seat together and locks at 95, 105, and 118 degrees. A rear or underside knob controls tilt resistance for user weight, with a practical setting range reaching 136 kg. The independent headrest offers 60 mm of height movement and 20-degree angle adjustment for neck support. The chair also swivels and rolls for easy movement at a workstation. The recommended user weight capacity is 136 kg, the recommended maximum user height is 190 cm, and the caster set is rated for 160 kg total dynamic load. Net weight is 19 kg. These features make the chair appropriate for open-plan desks, private offices, and home offices where eight-hour seated task support is required. Procurement teams can consider this unbranded model for bulk workstation projects preferring blue mesh upholstery, black bases, and standard caster replacement parts. Each set ships in two cartons, with packaged gross weight of 23 kg, reference carton dimensions of 850 x 420 x 720 mm, and reference carton volume of 0.26 cubic meter per set. Reference assembly time is 40 minutes per set.
