Product Description

The High-Back Mesh Ergonomic Office Chair with Fixed Armrests and Polished Aluminum Base is a professional swivel task chair designed for long-duration desk work in both commercial and residential settings. Presented in grey mesh with a grey fabric seat, it has a tall, contoured backrest, padded seat, fixed T-shaped armrests, and a polished five-star base, creating a clean executive appearance that complements modern workstations. Its layout balances support with an open visual profile. The back uses grey horizontal-mesh textile tensioned within a black polymer outer frame, while the lumbar-contoured shape provides structured support across a 240 mm zone. The grey fabric seat is built over molded polyurethane foam at 45 kg/m3 density with 40 percent rebound, and the finished cushion is 90 mm thick. Backrest padding is 70 mm thick. Fixed black polymer T-armrests include soft-touch pads and steel fixing inserts, with 540 mm of clear width between them and elbow support positioned 220 mm above the seat. Construction combines impact-resistant polymer components with metal reinforcement. The underside features a black polymer cover enclosing a steel synchro-tilt mechanism. The polished die-cast aluminum five-star base has a 3.5 mm structural wall section and supports black twin-wheel casters. A black-coated steel telescoping gas lift provides seat-height adjustment, while the 360-degree swivel seat and five casters support movement around a workstation. The chair has a net weight of 18 kg and is rated for users weighing up to 136 kg and users 190 cm tall. Practical controls are integrated beneath the seat. Pneumatic height adjustment offers 100 mm of travel, allowing the seat to be set from 430 to 530 mm. The synchro-tilt mechanism moves the seat and back together, reaches a 120-degree back angle, and includes tension control. These functions make the chair suitable for open-plan offices, workstation clusters, meeting rooms, and home offices requiring an 8-hour swivel task chair. For procurement, the unbranded model EOCH-MESH-HB-PA01 is supplied as one set across two cartons, with a packaged gross weight of 23 kg and a reference assembly time of 40 minutes per set. Buyers should specify the grey mesh and fabric seat configuration for general staff seating and confirm hard-floor or carpet-specific casters before ordering. The overall footprint is 670 x 680 x 1180 mm, allowing straightforward planning around standard desks and benching layouts.
