Product Description

The Blue Mesh Ergonomic Task Chair with Height Adjustable Arms is a high-back office seating solution designed for focused desk work in commercial and residential settings. Its blue mesh back and matching seat create a contemporary visual profile, contrasted by a black molded frame, arm structure, central gas lift, and five-star caster base. The chair has a 680 by 680 mm footprint and an overall height of 1180 mm, with a tall backrest, integrated lumbar zone, and padded headrest that give the design a supportive task-oriented stance. The clear width between armrests is 540 mm, supporting an open seating layout while retaining defined arm support. Construction centers on a blue flexible polyester mesh back tensioned over a black molded polymer frame with an internal lumbar support carrier. The seat uses a blue mesh or woven fabric face over shaped cushioning, including 60 mm molded polyurethane foam at 45 kg/m3 density, set within a 12 mm molded polypropylene seat pan reinforced with a steel plate. The finished cushion is 90 mm thick, while the backrest padding is 70 mm thick. Arm pads are 250 mm black polyurethane soft pads mounted on black powder-coated steel or glass-fiber nylon posts and side brackets. A 50 mm black steel telescoping gas cylinder connects the seat to the caster base. Functional features support active desk use. The chair provides 360-degree swivel, an 80 mm gas-lift seat-height stroke operated by an under-seat lever, and a multi-position synchro tilt with an 18-degree maximum recline and lock positions. A front knob controls tilt tension for users up to 150 kg. The integrated flexible lumbar zone offers 30 mm depth support across a 240 mm high support area. The headrest has 40 mm height travel and a 25-degree angle tilt, while the fixed-width 2.5D arm pads offer 20 mm fore-aft adjustment. The chair is rated for a recommended user weight capacity of 150 kg and suits users from 160 to 190 cm in height. This model fits open-plan workstations, private offices, hot-desking areas, home studies, computer rooms, and task-focused meeting spaces. It is intended for desk work rather than lounge-style conferencing, and its compact footprint works well where movement between stations is common. For wood, tile, vinyl, or low-pile carpet, procurement teams should specify soft-tread casters to reduce floor marking. Buyers should plan for flat-pack delivery in two cartons per set, with a packaged gross weight of 23 kg and a reference assembly time of 40 minutes per chair. The reference carton dimensions are 850 by 420 by 720 mm, and the packaged volume is 0.26 cubic meters per set. The listed 20GP container loading is 135 sets at 85 percent space utilization. Durability references include 100,000 seat-impact cycles, 100,000 caster-rolling cycles, and 120,000 backrest cyclic-load cycles. As an unbranded model, OC-MESH-BL-HA-01 is best suited to buyers seeking a practical blue mesh task chair with adjustable support for shared or individual workspaces.
