EO Active Perch Seat
The eo Active Perch Seat is an active seating option for sit-stand work environments, providing a compact support point for users who want to alternate between standing and perching.

The primary risk is not sitting itself, but prolonged sedentary duration without movement.

S P A S™ Sit Perch Active Stand
The S P A S™ Model mitigates this risk by encouraging posture variation and dynamic movement across the workday. Instead of relying on any single “ideal” posture, S P A S™ supports natural variation between neutral and supported working positions.
The S P A S™ Model defines four primary posture states:
Sitting, Perching, Active, Standing
By intentionally alternating between these S P A S stages, the body is encouraged to shift load, vary joint angles and engage in continuous micro-movement throughout the workday.
Dynamic movement is supported through:
- Regular posture transitions
- Small, frequent adjustments in joint angle and weight-bearing
- Natural shifts between supported, semi-supported and upright postures
This approach helps reduce prolonged static duration while supporting comfort, circulation, performance and postural sustainability at work.
Its height-adjustable gas-lift design allows the seat to suit higher work surfaces and standing desks, while the pivot function encourages controlled movement rather than fixed static sitting.
Adopting a stable tripod stance and weighted non-slip base provide a secure foundation as the user shifts between Sitting, Perching and Active Standing ( S P A S )
A low-profile carry handle supports practical daily use in flexible workspaces.
This eo Active Perch Seat is an active movement perch, not a full-time replacement for a conventional ergonomic task chair. Best for movement, perching and sit-stand transitions.
Primary System: S E A T™

S E A T™ - Pelvic Support
Improve pelvic stability
Maintain spinal alignment
Supported seat comfort
What this means for you when the 4 elements are aligned
| Corrected screen alignment → reduced neck strain |  - S E E™ |
| Better pelvic support → less lower back fatigue | - S E A T™ |
| Arm positioning → reduced shoulder load |  - A R M S™ |
| Movement support → reduces static load |  - S P A S™ |
The core is R E P O S E™ - the natural low-load comfort
achieved when Vision Support Reach and Movement are aligned.

EO Active Perch Seat
Who is it for?
For users who work between sitting and standing. Suitable for people using sit-stand desk, high benches, collaborative work points, short-duration task zones or flexible workstations. It is best suited to users who want to shift between Sitting, Perching, and Active Standing ( S P A S )
Suitable Environments
Clinical rooms, treatment areas, laboratories, active workstations, sit-stand desks, design studios, high benches and compact work zones requiring mobility and posture variation. Sit-Stand workstations, agile offices, touchdown work points, reception counters, drafting benches, design studios, collaboration zones, training areas, laboratory-style benches, healthcare supports spaces, compact work areas and flexible office settings where users move frequently between tasks.
“Our P O S T U R E Comfort Model™ helps you
achieve sustainable comfort through four integrated
elements - working together to support Natural R E P O S E™…
Ergonomic task chairs are designed to support seated posture, stabilise the pelvis and enable adjustable comfort during desk-based work.
Problem to Solve
Solves the “static posture gap” between sitting and standing. In a sit-stand workstation, users often alternate only between a task chair and full standing. The eo Active Perch Seat adds a third working mode — supported perching — helping users shift load, maintain foot contact, and move more naturally through Sit, Perch, Active and Stand postures under S P A S™.
