Who Should NOT Choose the Liberty Chair

Liberty may not be the best fit for users who prefer:

• Plush cushioning instead of mesh
  
• A built-in headrest
  
• A heavier, more traditional executive look
  

Those users may be better served by the Freedom Chair or Freedom Headrest.

Why Professionals Choose the Liberty Chair

Professionals choose Liberty because it solves one of the biggest problems in task seating—manual adjustments. Instead of needing to dial tension, set lumbar height, and micro-adjust recline, Liberty handles everything automatically.

Its tri-panel mesh back provides breathable, adaptive support that’s nearly impossible to collapse, making it ideal for multi-user environments like conference rooms and hybrid workspaces. Meanwhile, its weight-sensitive recline encourages healthy movement and keeps users balanced during computer work, meetings, and long sessions at the desk.

As an ergonomic mesh task chair, Liberty offers the rare combination of breathable comfort, automatic lumbar support, and a minimal, design-forward profile that works in nearly any space.

Liberty vs. Freedom vs. Traditional Task Chairs

Liberty Chair
Best for breathable mesh comfort, adaptive lumbar, shared seating, and hybrid environments.

Freedom Chair
Sculpted foam cushioning, automatic recline, and optional headrest—ideal for long-duration focused work.

Traditional Task Chairs
Rely on multiple levers, tension knobs, and manual adjustments. Liberty eliminates complexity with automatic ergonomics.
