Product Description

The Green Mesh Ergonomic Executive Office Chair with Headrest, model EMH-GM5D-01, presents a high-back executive silhouette with a breathable green flexible woven backrest and matching curved headrest against black structural framing. Its black upholstered seat, black arm pads, and five-star base create a disciplined two-tone appearance suited to professional interiors. The contoured back frame, padded headrest with black lower trim, and open mesh surface give the chair a layered visual profile while preserving airflow during extended seating. Overall dimensions are 680 x 680 x 1310 to 1320 mm, the clear width between armrests is 540 mm, and the finished cushion thickness is 90 mm. Construction balances comfort and structured support. The seat uses black woven fabric or performance mesh over a contoured cushion with 70 mm molded polyurethane foam. Beneath the cushion, a molded plywood or glass-filled polypropylene load pan provides the inner support. Behind the green backrest mesh, zone-molded lumbar and upper-back padding adds localized cushioning, including a defined lumbar support zone. The perimeter frame is made from black glass-filled nylon or reinforced polypropylene, while arm supports combine black injection-molded resin or steel-reinforced posts with soft-touch polyurethane pads. A steel gas lift and twin-wheel casters complete the mobile structure. Functionality is centered on adjustability and posture variation. The chair offers full 360-degree swivel, lever-operated pneumatic seat-height adjustment from 460 to 540 mm, and synchronized recline with linked seat movement. The back reclines up to 18 degrees, and a multi-position tilt lock secures upright or selected reclined angles. A rear rotary knob controls tilt tension for users from 50 to 150 kg. The headrest adjusts in height and angle, with 60 mm of vertical travel, and the four-dimensional arm pads adjust in height, width, slide, and rotation. The chair is suitable for private executive offices, open-plan workstations, home studies, hot-desking areas, meeting or video-call rooms, and IT or design workstations. Its high back, headrest, lumbar support, and mobility make it appropriate for daily computer work, collaboration, documentation, coding, and design tasks, with a recommended daily usage target of 8 hours and support for users from 160 to 190 cm tall and up to 150 kg. Procurement teams should plan for one set supplied in two cartons, with packaged gross weight of 23 kg and reference assembly time of 40 minutes per chair. The unbranded specification is useful for projects where bulk layout consistency, adjustable ergonomic features, and a distinctive green mesh finish are priorities. Site planning should account for the 680 mm footprint, rolling clearance around desk bays, and suitability across users who require different seat, arm, headrest, and recline settings.
