Advanced Ergo Seating System

Senior wheelchair users tend to have weaker upper body control which leads to slouched posture or downward-facing head position. The Ergo Seating System addresses this common issue by incorporating scientifically proven seating angles, effectively promoting equilibrium in body posture. This innovative design is tailored to passively seated individuals in wheelchairs, facilitating an expanded field of vision, elevating social interactions, and mitigating chronic sitting discomfort.
