What are the key features of the Quantum Edge 4 power wheelchair?
The Quantum Edge 4 combines advanced driving technology with practical features for everyday use.

Optional powered seating functions and a choice of colours allow further personalisation.
Is the Quantum Edge 4 suitable for indoor and outdoor use?
Yes. The Quantum Edge 4 is designed for manoeuvrability indoors and confident driving outdoors. Its mid-wheel-drive configuration and 579 mm turning radius help it navigate tighter spaces, while its independent Smooth Ride Suspension and ability to climb obstacles up to 73 mm support travel over suitable uneven surfaces. Suitability depends on the user’s environment, the terrain and the wheelchair’s configuration.
What seating and positioning options are available on the Quantum Edge 4?
The Quantum Edge 4 offers TRU-Balance 3 seating, with powered positioning options that can include tilt, recline, seat elevation and powered leg positioning, depending on the selected configuration. Optional iLevel seat elevation raises the seat by up to 12 inches. These functions can help users adjust their position for comfort, access and everyday activities. The most appropriate seating configuration should be selected according to individual clinical and functional requirements.
What is the maximum speed and weight capacity of the Quantum Edge 4?
The Quantum Edge 4 has a maximum speed of up to 7 mph (11.26 km/h) in its standard configuration, with a reduced maximum speed of approximately 4.5 mph (7.2 km/h) when using iLevel seat elevation. The product page lists a weight capacity of 3 stone 4 lbs; prospective users should confirm the correct maximum user weight with LCS before selecting a configuration, as this specification appears inconsistent with typical power wheelchair capacities.
