The Sihoo M59AS brings a breath of fresh air to your workplace - quite literally. The full-surface mesh construction ensures optimum air circulation and prevents unpleasant sweating, even during long periods of sitting. The two-part backrest follows the natural S-shape of your spine and offers customised support from the upper to the lower back. The dynamic lumbar support adapts to your movements and provides continuous relief. It gets even smarter with the 3D-adjustable armrests, which can be adjusted in height, depth and angle - and can be easily folded up when you need more space. Comfort is not neglected either: the saddle-shaped seat distributes the pressure evenly over the hips and thighs, ideal for long, fatigue-free sitting. The height-adjustable headrest with rotation joint offers you precise neck support - whether you are working upright or leaning back. A clever extra: the integrated clothes hanger on the back so that your jacket or bag is always within easy reach and wrinkle-free. Robust materials and simple operation round off the ergonomic overall package - for long-lasting quality you can rely on.
