Manoeuvrability at home and outdoors

With a 610mm base width and 579mm turning radius, the Edge 4 is designed to negotiate indoor spaces while offering the suspension and wheel size needed for everyday outdoor journeys.

Its independent SRS suspension and large castors help smooth the ride over uneven pavements, grass and gravel. Suitability for particular routes and surfaces will depend on your configuration and should be explored during assessment.

Seating and powered positioning options

The Edge 4 can be specified with different seating packages to suit your support requirements and daily activities.

TRU-Balance 3

A configurable seating system with options including powered tilt, recline, elevating leg supports and iLevel seat elevation.

TRU-Balance 4

Offers additional positioning options, including configurable anterior tilt and memory seating. Suitable configurations can also include an articulating powered foot platform.

Anterior tilt moves the seat forwards to support particular reaching activities or transfers where clinically appropriate. Our team can advise whether this function is suitable for you.

Optional iLevel seat elevation

With up to 305mm / 12 inches of lift, iLevel can help you reach higher surfaces and take part in conversations at eye level. Compatible configurations allow driving while elevated at speeds up to 4.5mph, subject to operating conditions.

All powered functions are selected as part of your specification; they are not included on every Edge 4.

Controls configured around you

The Edge 4 offers Q-Logic control options, with compatible alternative controls available for users who need a different approach to driving.

During assessment, we consider joystick position, hand function, access to seating controls and whether attendant controls would be useful. We can also discuss additional connectivity options where appropriate.

Brief technical specification

Range varies with user weight, terrain, battery condition, tyre pressure and use. Overall dimensions, seat sizes and seat height depend on the selected seating, accessories and configuration.

Why buy your Quantum Edge 4 from Unique Mobility?

An individual assessment

Choosing a prescription powerchair starts with understanding how you live and what you need your chair to help you do.

We discuss your current equipment, everyday activities, home environment, outdoor journeys, transfers and transport arrangements. Our assessment considers your measurements, posture, support requirements and ability to operate the controls.

We then help you explore suitable seating, powered functions and accessories, with demonstration arrangements discussed according to availability. Your final specification is agreed around your individual requirements.

Specialist clinical seating and Occupational Therapy

If you require more detailed postural or seating support, we can arrange an assessment with our in-house Occupational Therapist.

Our specialist clinical seating services can include:

• Assessment of posture, comfort and positioning.

• Advice on pressure management.

• Selection of suitable cushions, backrests and additional supports.

• Consideration of bespoke seating where required.

• Pressure mapping, where appropriate, to assess pressure distribution and help inform seating recommendations alongside the wider clinical assessment.

Clinical services are arranged according to your needs, with any applicable fees explained before booking.

Local advice and ongoing aftercare

Our teams in Exeter, Plymouth and Launceston support customers across Devon and Cornwall, with specialist services also covering West Somerset.

From initial advice and configuration through to handover, servicing and repairs, we provide ongoing support to help you get the most from your powerchair.
