The Sihoo Doro C300 scored highly in our test with its various adjustment functions, even if there is still room for improvement. It enables a sitting position that can be adjusted in various ways and offers good back support, especially with the dynamic and self-adjusting lumbar support. This benefits people who work at a desk all the time, as they can sit comfortably on the chair for many hours. Ultimately, the fit depends primarily on your height. We don't quite agree with the manufacturer's specifications. From a good 180 cm, the height adjustment of the backrest and headrest is not sufficient according to our findings. However, people up to 180 cm sit comfortably according to our impressions. The optional footrest is practical and pleasant for everyday office use and invites you to relax when needed. Overall, the Sihoo Doro C300 made a good impression in our test, with some limitations.
