3D Headrest

Drop it to the lowest setting and it even catches your shoulders.
Backrest & lumbar support
High mesh back keeps things cool and springy. The upper backrest follows your natural curve while the lower zone works with the dual lumbar pads to cradle your lower back.
Two adaptive, wraparound lumbar wings give your waist full-contact support. Use the twin knobs to infinitely adjust height (up to 5 cm) and depth (about 3 cm).

3D flip-up style Armrest

Soft, slightly rotatable arm pads keep your forearms happy.
Weight-Sensitive Recline
A weight-sensitive tilt mechanism automatically matches tension to your body weight.
Lean back up to 135° with multi-angle lock (98°/105°/125°/135°) plus 5 cm seat depth adjustment.
All controlled via a clean cable module that handles tilt, lock, height, and slide in one place.
