The Sihoo Doro S300 is a high-performance ergonomic office chair that fuses cutting-edge technology with award-winning aesthetics. Crafted from a single piece of aluminum alloy and winner of the German Design Award, it stands out for its sleek, sculptural form. At its core is the 6th-generation anti-gravity mechanism, enabling a smooth, weightless recline that adjusts effortlessly without the need to lock into position.

Engineered for comfort, the dual dynamic lumbar support system adapts to your posture and body shape, while the seat and armrests move in coordination with the backrest to reduce pressure on your thighs. The breathable mesh—made from Italian Dupont TPEE—ensures ventilation, elasticity, and long-lasting durability. With fully adjustable 6D armrests, a supportive headrest, and precision tuning for every part of your body, the S300 offers a truly custom fit. Certified by TUV Rheinland and BIFMA, it meets global standards for quality and safety. Backed by a 5-year warranty, this chair is built for lasting comfort and support.

Care Instructions

To keep your ergonomic office chair in top condition, regularly dust with a soft cloth and vacuum fabric surfaces using a brush attachment. Spot clean spills immediately with a damp cloth and mild detergent—avoid harsh chemicals or abrasives. Check and tighten screws or adjustment knobs periodically to maintain stability. For smooth movement, clean the caster wheels and lightly lubricate if needed. Keep the chair away from direct sunlight and excessive moisture to preserve the upholstery and frame.
