Buying an ergonomic chair can feel hard because many models look alike. I wanted to know if the SIHOO Doro S100 or the SIHOO Doro C300 was the better choice for daily work. I spent time comparing both chairs for long writing sessions, video calls, and normal office tasks. Each chair has its own strong points. The right one depends on how you sit and what kind of support you need. In this review, I share what I found after comparing both models. If you want a quick answer, both are excellent, but they are made for different users.
