Who Is It For?
Suitable for users who:
- require a larger or heavy-duty ergonomic chair
- work in multi-shift or extended-use environments
- spend substantial periods seated at a workstation
- need greater seat width and depth
- require adjustable arm and head support
- want control over seat angle, recline and seat depth

Problem to Solve
Standard task chairs may not provide the size, structural capacity or adjustment range required by larger users or demanding multi-shift workplaces.
The Ranger provides a broader, reinforced seating platform together with multiple adjustments.
The seat slider helps accommodate different upper-leg lengths, while forward seat tilt provides additional control over pelvic and seat angle. The synchronised mechanism allows the seat and backrest to move together as the user changes posture.
Adjustable arms and headrest provide additional support according to the user and task.
