Product Description

The High-Back Black Mesh Ergonomic Office Chair (model ERG-MSH-A3006-BLK) delivers structured, professional seating designed for extended daily use across commercial and residential work environments. Its cohesive all-black finish features a tall mesh backrest paired with a generously padded fabric seat, creating a streamlined silhouette that aligns with modern workplace aesthetics. The 5-star caster base supports a central swivel joint that enables full 360-degree rotation, while height-adjustable armrests sit flush to the seat’s sides, and an adjustable mesh headrest crowns the high back frame to complete the ergonomic layout. Construction uses durable, purpose-built materials selected for long-term regular use. The backrest uses breathable black polyester mesh stretched over a glass-fiber reinforced nylon internal frame, paired with a contoured adjustable lumbar support zone. The seat is built on a rigid high-density fiberboard pan, topped with molded high-density polyurethane foam and upholstered in black woven polyester fabric. Armrests feature soft polyurethane pads mounted on polypropylene support posts, while the 2.0mm thick glass-fiber reinforced nylon 5-star base is fitted with smooth-rolling nylon dual casters. A Class 3 chrome-plated steel gas lift and 2.5mm thick stamped steel tilt chassis form the chair’s core structural mechanism, supporting reliable daily adjustment. Practical functionality is tailored to support comfortable posture across long work sessions. Pneumatic seat height adjustment allows users to set the seat to a desk-aligned position, while the kneel-tilt backrest reclines to a 125° maximum angle with lockable positions, paired with an under-seat rotary knob to adjust tilt tension to match individual user weight. The headrest adjusts for both height and angle to support the neck, the contoured lumbar zone adjusts to cradle the lower back, and armrests move vertically to provide customized elbow support. The breathable mesh back reduces heat buildup during extended seated periods, while the swivel and caster design lets users move easily within their workstation without standing. This chair is well suited for a range of settings. It supports 8-hour daily desk work for professional staff in private offices, fits standard workstations in home offices for remote work and study, and coordinates with modern decor in open-plan office task stations. It is an appropriate choice for call centers and customer service areas where staff work extended shifts, and its polished appearance and smooth swivel function make it suitable for conference and meeting room collaborative use. It pairs optimally with 760mm high standard office desks to maintain proper ergonomic positioning. Procurement teams and individual buyers should note the chair ships as one set across two cartons, with a reference assembly time of 40 minutes per unit. It carries a 3-year warranty, with a maximum recommended user load of 130kg. For bulk orders, 135 sets fit in a 20GP container at 85% space utilization, supporting efficient large-space furnishing projects. When planning space layouts, teams can reference the chair’s overall footprint and clear armrest width to ensure sufficient clearance around workstations, and verify desk height compatibility to maximize ergonomic benefit for end users.
