Ergo 3

The Next Generation of Lightweight Mobility

The Karma Ergo Series blends ergonomic excellence with lightweight mobility, offering natural balance from head to lower back. This innovative design reduces the effort needed to maintain an upright posture, enhancing social interactions with more comfort and vitality.

At the heart of this transformation lies the patented Ergo Back and market-proven S-Ergo Seat. Discover the future of seating luxury with the Ergo 3 – where form, function, and well-being converge in perfect harmony.

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.

Ergo 3 features the optimal seating angles to:
– Promote a stable, healthy posture
– Alleviate chronic sitting discomfort
– Enhance field of vision
– Improve social interactions

Relaxed Sitting, Healthy Living

Patented Ergo Lumbar Support

Karma’s innovative S-Ergo Backrest enhances both comfort and stability, allowing users—especially those with reduced muscular endurance—to maintain proper, healthy posture with ease.

Karma’s Ergo Series lightweight wheelchairs include a set of adjustable curved inserts that provide direct lumbar support and maximize comfort.

ntuitive Design

Designed with both users and caregivers in mind, all movable parts are highlighted in high-visibility orange for easy identification and operation.

Push & Pull Brake System

Just push the attendant brake to park the chair, and pull to unlock. Ideal for caregivers who can’t continuously bend over to park the wheelchair.

Flip-Back Armrests

Makes it easy to get on and off the wheelchair or roll closer to a table or desk.

Detachable Swing-Away Footrests

Allows for easy transfer, on and off the wheelchair and detaches with no tools required

Multi-Functional Side Guards

Discreet, easily accessible pockets are elegantly integrated into the inner sides of the side guards for added convenience, while the outer sides feature reflective accents to enhance visibility and safety outdoors.

Lightweight Innovation

Despite its many innovative features, Ergo 3 is one of the lightest wheelchairs on the market, with a total weight of just 11.9 kg (about 26 pounds) in its base configuration.

Optional Patented Ergo Anti-Tippers
