This high-back breathable mesh ergonomic office chair, model ERG-OF-740-BLK-MESH, delivers balanced support and professional styling for a wide range of work environments. Unbranded for flexible integration across diverse interior schemes, the chair presents a sleek, streamlined silhouette defined by its contoured mesh back, structured padded armrests, and polished five-star base, with clean lines that complement both contemporary and traditional office decor. Assembled, the chair measures 680 x 740 x 1230 mm, with a high 600 mm backrest, 500 mm deep seat, and proportioned 295 x 50 mm headrest that creates a cohesive, upright profile without unnecessary bulk. The chair is built for long-term daily use, combining durable, performance-focused materials across every component. Its backrest uses reinforced breathable woven polyester mesh tested to 60,000 double rubs of abrasion resistance, stretched over a glass fiber reinforced nylon internal frame with 4mm rib thickness for consistent flex. The seat pairs a 40 density high-resilience molded polyurethane foam core with a breathable mesh overlay, supported by a 3mm thick steel plate synchro-tilt chassis. The polished die-cast aluminum alloy five-star base features 2mm wall thickness, fitted with 50mm diameter polyurethane tread casters with nylon inner hubs rated for 100,000 rolling cycles, a Class 3 chrome-plated carbon steel gas lift with 65mm stroke, and armrests with soft polyurethane padded tops on rigid plastic frames. The chair holds a maximum user weight capacity of 150 kg, with a net weight of 23 kg. Functionality is tailored for ergonomic comfort across extended use: pneumatic seat height adjustment offers 65mm of vertical travel controlled by a side lever under the seat, adjusting seat height between 490 mm and 555 mm from the floor, with armrests reaching a maximum 235 mm above the seat surface. The backrest reclines to a 125° maximum angle with four lockable positions, paired with an under-seat rotating knob to adjust tilt tension to match user weight. The headrest adjusts 45° in tilt and 65mm vertically for targeted neck support, while a contoured adaptive mesh lumbar zone flexes with natural user movement. Full 360° swivel and smooth-rolling dual-wheel casters allow easy movement across both carpet and hard flooring. This chair is suitable for corporate open-plan workstations, where it supports 8-hour daily desk work with consistent posture support, as well as home office and remote work spaces where its compact footprint fits standard desk setups without excess space. Its polished professional finish also suits executive private offices, particularly paired with a 2.4 m executive desk, while its broad adjustment range accommodates diverse user needs in co-working and shared office spaces; the swivel and tilt functions further support natural interaction in conference and meeting rooms. For procurement teams, note that each unit ships in two cartons, with a packaged gross weight of 23 kg and total carton volume of 0.26 m³, allowing 135 sets to fit a 20GP container at 85% space utilization. Assembly requires 40 minutes per set, making it a practical choice for both small-scale fit-outs and large-volume office deployments.
