Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Lumbar Support presents a professional, streamlined seating solution in a coordinated black finish with a polished aluminum base. Its high-back form combines a flexible woven mesh backrest tensioned within a black polymer outer frame, an upholstered foam seat, fixed upright armrests, and a padded curved headrest. The five-star base and twin-wheel casters give the chair a familiar executive silhouette while supporting a smooth, mobile office layout. The clear width between armrests is 540 mm, with a 90 mm finished seat cushion and 70 mm backrest padding. The defined lumbar support zone is 240 mm high, reinforcing the chair’s focus on structured lower-back contact. Construction balances breathable support with durable components. The back uses black flexible woven mesh, while the seat is finished in black woven fabric over molded foam set on a load-bearing shell; the seat foam density is 45 kg/m3. The frame and arm supports are made from black molded polymer or glass-fiber-reinforced nylon. The polished die-cast aluminum five-star base uses five outward legs, paired with black twin-wheel swivel casters featuring hard treads and metal mounting stems. A chrome-plated steel gas cylinder with a black upper collar connects the seat to the base. The chair has a net weight of 19 kg and a recommended user weight capacity of 150 kg, matched by a Class 4 gas-lift dynamic rating of 150 kg. Material reference values include a back mesh tensile rating of 350 N/50 mm, a fabric abrasion resistance target of 50,000 Martindale cycles, and a caster rolling durability target of 100,000 cycles. Functional features suit extended desk-based work. A pneumatic lever provides seat-height adjustment from 440 mm to 500 mm through a 60 mm stroke. The synchronized tilt mechanism offers a 15-degree rear recline with tension control, while the recline angle reference is 125 degrees with three suggested lock positions. The rigid rear lumbar support and padded curved headrest separately address lower-back and neck contact, and the swivel base enables easy movement within a workstation. The reference daily use duration is 8 hours per day, subject to confirmation by ergonomic testing. This unbranded model, EM-HB-MESH-01, is appropriate for private offices, open workstations, meeting spaces, home studies, and executive seating paired with a 2.4 m desk. Procurement teams should plan for two cartons per set, a packaged gross weight of 23 kg, 0.26 cubic meters of package volume, and a reference assembly time of 40 minutes per chair.
