Product Description

The EHC-HB-GRY-01 is an unbranded high-back ergonomic mesh office chair designed for task-focused seating in commercial and residential work environments. Its appearance combines a grey mesh back, grey woven fabric seat, black structural components, and a polished aluminum five-star base, giving it a contemporary look that fits neutral office interiors as well as modern home workspaces. The high-back carrier supports the upper body, while a curved mesh-covered headrest sits on a central height-adjustable bracket. Black polymer armrests, mechanism housing, gas-lift detailing, and twin-wheel casters provide visual contrast and complete the streamlined layout. Construction is based on a black framed high-back carrier fitted with grey horizontal-weave elastic mesh. The seat uses a molded foam cushion wrapped in grey woven fabric and finished with a rounded waterfall front intended to support the thighs comfortably. The finished cushion thickness is 90 mm, and the backrest padding thickness is 70 mm. The black rigid polymer armrests include height posts and soft-touch flat pads, with a clear width between armrests of 540 mm. Under the seat is a black multi-position tilt mechanism with a visible seat plate and back linkage, connected to a black gas lift with polished chrome lower sleeve and a polished aluminum five-star base. Black 60 mm twin-wheel casters are fitted for mobility. Overall dimensions are 670 x 680 x 1290 mm. The chair is built for practical daily adjustment. Pneumatic seat-height adjustment offers 90 mm of travel, allowing seat height from 450 to 540 mm through an under-seat lever. The synchronized seat-and-back tilt provides 25 degrees of recline travel and can be locked in upright, mid-recline, and full-recline positions. The headrest moves 60 mm vertically to help align support with the cervical spine, while the 240 mm lumbar support zone addresses the lower-back area. A 360-degree swivel seat and five twin-wheel casters support movement on hard floors and low-pile carpet. The recommended user weight capacity is 150 kg, and the chair net weight is 19.5 kg. This model is suitable for executive desks, open-plan workstations, and home offices where high-back support, adjustable head support, recline movement, and rolling mobility are required. It is especially relevant for computer-based work and long-duration task use. Procurement teams should plan for assembly and receiving logistics: the product is supplied as one set across two cartons, with a packaged gross weight of 23 kg, reference carton volume of 0.26 cubic meters per set, and a reference assembly time of 40 minutes per set. Buyers should also verify delivery access, assembly responsibility, and seating compatibility with intended desk height and floor type.
