What defines it

01

Seat from 46.5 to 55 cm

It is the first filter for any chair: your popliteal height (≈ 25% of your height) must fall within this range. The chair filter checks it against your measurements in one click.

02

The lumbar that adjusts itself

Active lumbar support: it follows the curve of your back as you move, without you having to reposition it. It is the spec you notice most from the sixth hour on.

03

5-year warranty · up to 150 kg

The declared maximum weight is the frame's test limit, and the warranty is the best clue to its real durability.
