Verdict. The Sylphy is Okamura's premium ergonomic chair, from a Japanese brand with a strong reputation in high-end office furniture. Its signature is the S-curve backrest, which supports the lumbar and thoracic areas with a line designed to follow the spine, and a synchro mechanism that reclines up to 23 degrees with a 10-degree forward tilt adjustable by dial. The seat cushion is multi-density, softer at the front and firmer at the back. It isn't sold on Amazon Spain and usually ships to order with long lead times, so it's a specialist-channel purchase rather than a consumer one, and the price matches that category.

What the community says

Highly regarded among those who know Japanese office ergonomics: the S-curve backrest and the fit to different builds are cited as its strengths. The consensus is that it competes in the premium league, with the drawback of an indirect purchase channel outside Asia and little public information on maximum load and warranty.
