The Modern Two-Tone High-Back Ergonomic Office Chair (model EOH-5012-CW) is an unbranded public furniture piece with a sleek, professional two-tone aesthetic: black padded faux leather covers all user contact surfaces, paired with a crisp white outer back shell for a contemporary look. Its tall, contoured segmented high back provides integrated lumbar support, matched to a contoured waterfall-edge seat and fixed padded armrests, all anchored to a polished chrome five-star base fitted with black non-marking casters for a balanced, streamlined silhouette that fits modern interior palettes. The chair is built for long-term regular use, with a reinforced steel internal frame paired with a multi-ply plywood seat pan. Molded polyurethane foam forms the core cushioning, with a softer density layer for the seat and a firmer density layer for the backrest to deliver targeted support. The chrome-plated steel base connects to a Class 3 pneumatic lift and steel plate tilt mechanism, with durable nylon twin-wheel casters, and reinforced polyester stitching on the 1.0mm thick faux leather upholstery to withstand regular contact. Core functional features support comfortable daily use over full 8-hour shifts: pneumatic seat height adjustment accessible via a side lever lets users align the seat to standard desk heights, while a 360-degree swivel enables easy reach to surrounding work surfaces. The tilt mechanism offers 15 degrees of backward recline, with an upright position lock and adjustable tension knob to suit different user preferences, while the waterfall seat edge reduces pressure on the back of the thighs during extended sitting. The non-marking casters roll smoothly on hard wood and low-pile carpet floors without leaving scuffs. This chair works across both residential and commercial settings: it fits home office studies paired with wood or composite computer desks, supports employee workstations in open-plan small to mid-sized offices, complements junior to mid-level executive private offices, holds up to frequent use in shared co-working spaces thanks to its easy-to-clean upholstery, and offers polished, comfortable seating for small to medium conference rooms. For procurement planning, note the chair ships in knock-down packaging, with an 30-minute assembly time using basic included tools and illustrated instructions. Structural components carry a 3-year warranty, and the chair supports a recommended user weight of 136 kg. Bulk orders can load 180 units per 20ft container or 440 units per 40HQ container, with a net chair weight of 18 kg for easy deployment during office fit-outs.
