The Sihoo M18 combines soft seating comfort with breathable ergonomics. The padded W-shaped seat ensures that your weight is evenly distributed and relieves pressure on your hips, even when sitting for long periods. There is also a mesh backrest that allows air to circulate - so you stay cool and focussed, even on warm days. The adjustable lumbar support allows you to customise your sitting position to suit your spine - horizontally and vertically. The height of the armrests can be adjusted to keep your shoulders relaxed and your posture correct. The headrest is also adjustable and adapts perfectly to your neck, regardless of whether you are working or leaning back. Thanks to the backrest tilt of up to 126°, you can take a little break at any time. And with its sturdy construction and high-quality materials, the M18 is made to last for many productive years. Whether for focussed work or relaxed leaning back - the SIHOO M18 brings ergonomic comfort exactly where you need it.
