The High-Back Grey Mesh Ergonomic Office Chair with Retractable Footrest, model ERG-OFC-MSH-FR-700, is an unbranded public and office seating solution built for sustained comfort across professional and domestic work settings. Its streamlined, contemporary silhouette features a tall tensioned light grey mesh backrest framed in glass-fiber reinforced nylon, paired with a contoured mesh-wrapped padded foam headrest and soft PU-padded armrests. The light grey reinforced nylon five-star base fitted with black dual-wheel PU casters anchors the design, with neutral grey finishes that coordinate seamlessly with modern interior palettes. Overall dimensions measure 635 x 765 x 1260 mm, with a 515 mm wide, 500 mm deep seat, 580 mm tall backrest, and 700 mm wide five-star base, creating a balanced footprint that fits neatly around standard work surfaces. Construction prioritizes durability and supportive performance: the seat cushion uses a 45mm thick core of high-density molded polyurethane foam rated at 50 kg/m³, the chrome-plated Class 3 steel gas lift delivers smooth vertical movement, and the 3mm thick steel plate locking chassis supports stable recline. The tensioned polyester mesh backrest delivers 50000 cycles of abrasion resistance, designed for long-term regular use. Functional features support tailored comfort for extended sitting: the chair offers full 360-degree swivel rotation centered on the gas lift column, pneumatic seat height adjustment with 100 mm vertical travel, 145-degree lockable backrest recline with adjustable tension control, 75 mm height-adjustable armrests with pivoting pads, 155 mm height and angle adjustable headrest, integrated segmented zoned lumbar support, and a fold-out sliding retractable footrest for use in reclined positions. It supports a maximum user weight of 136 kg and accommodates users up to 190 cm tall, with a net weight of 26 kg. This chair is suited for a range of spaces: corporate office workstations for 8-hour daily desk work, home office study spaces with standard desk setups, executive private offices, co-working shared spaces, and meeting rooms where swivel mobility supports collaborative discussion. It pairs optimally with 2.4 m executive desks.
