Floating Support Ergonomic Chair

Enlarged armrests with 90° flip, 360° rotation, forward/backward adjustment, and synchronized recline linkage; covered with skin-friendly PU leather for comfortable arm placement.
Adjustable in height (up to 36.5 cm), depth (10 cm), vertical (45 cm), horizontal (20 cm), and rotational joints for optimal head support and freedom of movement.
