Product Description

The Blue Mesh High-Back Ergonomic Office Chair with Headrest, model EOCH-MESH-BL-520, combines a structured high-back silhouette with breathable blue mesh and black support components. Its tall backrest follows a centered lumbar contour, while the padded mesh-covered headrest creates a continuous neck-support zone above the chair. Black T-shaped armrests frame a 540 mm clear seating width, and the five-star base with twin-wheel casters gives the piece a conventional task-chair footprint suited to desk-based settings. Overall dimensions are 650 x 650 x 1260 mm. Construction pairs upholstered comfort with a load-bearing metal structure. The seat uses blue woven mesh or mesh-textured fabric over a padded cushion built with 45 kg/m3 high-resilience polyurethane foam and a 60 mm cushion core; the listed finished seat cushion thickness is 90 mm. The backrest presents tensioned blue mesh within a molded framed surround, with 70 mm backrest padding and a 240 mm lumbar support zone. The headrest includes a padded cushion, blue mesh covering and an internal support board. Arm pads are black molded polymer, mounted on height-adjustable posts. Beneath the seat is a black molded polymer shell with steel reinforcement, connected to a black powder-coated steel telescoping gas cylinder. The base is specified as black glass-fiber-reinforced nylon or powder-coated steel, fitted with black polyurethane twin-wheel casters that use polymer forks and steel axles. Functionality centers on adjustable movement and support. The seat rotates through 360 degrees, and the pneumatic lift offers 80 mm of height travel controlled by an under-seat lever. A synchro tilt mechanism coordinates movement between the seat and back, with a 15-degree rear recline, lockable upright positioning and three recline positions. A rear knob provides tension control across five relative turns. The fixed-height headrest offers a 15-degree contoured surface, while the height-adjustable T-arms provide 70 mm of vertical pad travel. The chair has a rated user load of 136 kg and is recommended for users up to 1900 mm in height. The chair is suitable for open-plan workstations, home offices, manager desks, meeting and training rooms, shared-desk environments, and hard-floor workspaces including tile, wood, laminate and low-pile carpet. Its mobility supports rotation between tasks and rapid room reconfiguration. Procurement teams should note that this is an unbranded product supplied as one set in two cartons, with packaged gross weight of 23 kg and a reference assembly time of 40 minutes. The reference carton dimensions are 850 x 420 x 720 mm, carton volume is 0.26 m3 per set, and indicative 20GP loading is 135 sets at 85 percent space utilization. Material checks should account for the stated base option and mesh or mesh-textured seat upholstery, while project planning should include assembly, floor compatibility and shared-user adjustment needs.
