The Light Grey Dual-Lumbar Ergonomic Office Chair with Headrest (model ERG-DL-GRY-01) presents a streamlined, professional silhouette finished in a muted light grey palette that blends seamlessly with both modern commercial and residential interior schemes. Its balanced layout pairs a contoured backrest fitted with separate left and right lumbar support pads, a height-adjustable headrest, fixed T-shaped armrests, a generously padded seat, and a wide five-star base for stable, unobtrusive placement across workstation configurations. Built for consistent long-term use, the chair features a fiberglass-reinforced nylon frame, an injection-molded light grey PP five-star base, and a chromed steel gas lift cylinder with a protective black plastic sleeve. The seat is upholstered in woven grey polyester fabric, with a core of high-density molded foam for even weight distribution. Back support pads and the adjustable headrest are wrapped in matching fabric over resilient foam padding, while armrests use durable injection-molded PP tops. Smooth-rolling double-wheel casters combine a soft PU tread with rigid PP hubs, paired with the central gas lift to enable full 360-degree swivel rotation. Functional features are tailored for extended seated comfort: pneumatic seat height adjustment delivers 150mm of vertical travel via an intuitive under-seat lever, the backrest reclines to a 135-degree maximum angle with adjustable tension and an upright lock position, and the height-adjustable headrest travels 100mm vertically to support the neck and head. Dual independent lumbar pads promote proper spinal alignment, while the casters move silently across both hard and soft flooring surfaces. Fixed T-armrests are positioned to match standard desk elbow height for consistent upper body support. This chair is well-suited for a wide range of spaces, including private individual workstations, home office setups, open-plan office clustered task seating, call center workstations, co-working space hot desks, and residential study rooms for extended study sessions. Its neutral finish works with varied decor styles, and its standard footprint fits efficiently in dense workstation layouts. For procurement planning, note that each unit ships in two cartons, with an assembly time of 40 minutes per set. The chair supports a maximum recommended user weight of 150 kg, accommodates users up to 1880mm in height, and is rated for 8 hours of daily use. Fixed armrest height should be aligned with existing desk dimensions during space planning to ensure ergonomic fit for intended users.
