Refined ergonomics for modern executive workspaces.

Multi-dimensional adjustable armrest designed to fit different body types and sitting postures.
Features 6-position height adjustment, 360° swivel armrest surface and handle, and 2-position handle angle adjustment for stable, comfortable support.
