A year ago I genuinely thought office chair innovation was dead—everything looked the same, felt the same, and did the same thing. Then I got sent the Sihoo Doro S300, and after 365+ days of daily use (editing deadlines, late-night sessions, and long gaming stints), I can finally give you the kind of review you can’t fake in a one-week “new chair smell” first impression. In this video I show how the chair has actually held up, what’s impressed me, and what’s still annoying after living with it for a full year. The biggest surprise is the dual-pad lumbar system. I thought it was a gimmick at first, but around week three I realised I could stand up after hours of work and… no usual back pain. Over time you stop noticing it—which is exactly why it works—and you only appreciate it when you sit in a regular chair again. I also break down the “anti-gravity” recline (marketing name, but the mechanism is still smooth and silent), the spring suspension under the seat, the durability (nothing has failed), and the real caveats: ratchet adjustments that can’t be locked, armrests that get knocked out of place, no vertical lumbar adjustment for taller people, and a seat that can feel a bit hard over long sessions. My verdict: yes, I’d recommend it—just with a few very specific caveats depending on how you use your workspace.
