Is the Sihoo Doro S300 worth it?

Short answer: yes, but only at the right price. The Sihoo Doro S300 is usually worth considering at about $400–$600 new and roughly $250–$450 used/open-box if you want a highly adjustable ergonomic chair with a mesh build and a more premium feature set than typical budget office chairs. If it’s priced much above that, the value gets harder to justify versus better-known premium options. Prices move a lot, so check completed/sold listings and current retailer promos before buying.

Rule of thumb:

• New: good buy around $400–$500
• Used/open-box: good buy around $250–$400
• Walk away: if new is $650+ or used is $500+ unless it includes strong warranty/return protection

It’s a good fit if you want lots of adjustability and like the idea of a firmer, more structured ergonomic chair. It’s less appealing if you prefer a softer seat, want a simpler design, or can’t try it and return it easily.
