The 4Front® is a quiet, more responsive front-wheel drive power chair that features automotive-grade suspension with unprecedented comfort and ride quality.


Full Description

pThrough research, Quantum has found that consumers wanted a front-wheel drive chair with suspension that addresses real-world needs. The industry did not want another me-too product; they wanted suspension that addressed ride quality, performance, and safety. We looked at top suspension systems in other industries, especially automotive, and spent two years evolving what is now SRS (Smooth Ride Suspension) on the 4Front®.

The result is a power chair suspension that uses automotive-grade components and engineering to create performance and stability, with optimized user ride comfort. SRS is made up of four coil-over, gas-charged shocks that provide an ultra-smooth and quiet ride. The geometry in which the shocks are integrated into the power base allows independent wheel and caster travel, with the additional effect of stabilization delivering optional safe seat elevation up to 10″ at 3.2 mph.

With the 4Front providing unmatched performance over multiple terrains, Q-Logic 3 offers an advanced safety traction mechanism that will sense any reduction in traction. If the chair senses a reduction in traction, it will automatically revert to a 1.2 mph driving inhibit to ensure safe driving. The normal drive speeds resume once the user brings the chair to a stop and the joystick is centered.

Therapists from around the country test drove the 4Front at our annual design forums. The overwhelming response was that it drives much smoother than other front-wheel drive power chairs in the industry.

Cognitive Abilities

For safe use, users must understand cause + effect (action = result). Independent use requires directional understanding (i.e. moving control in one direction results in matching chair movement), problem solving (i.e. plan + coordinate movements to get from A to B), and judgment (ability to learn that if something is unsafe they should not do it).

Functional Abilities

Users must have adequate vision and be able to use either a joystick, head/tray array, breath control or a combination control. This chair is best for people with upper limb weakness/pain, poor trunk control, limited endurance, cardiopulmonary disease, and obesity. This chair may be unsafe for those with visual deficits and uncontrolled seizures.


Mid wheel drive power chairs have the smallest turn circumference of the power chair types and are better suited for indoor use where space is limited. This chair can be used both indoors and outdoors. However, because the centre of rotation is directly under the user, they can be less stable than other power chair types on uneven terrain.


Given its small turning circumference relative to other power chairs, this chair would be best for indoor activities like shopping, dining in restaurants, visiting art galleries and museums, and going to work or school. If using outside, activities done on flat level surfaces would be best.

Please speak with your healthcare provider and schedule an in-person consultation before purchasing this product, to evaluate whether it is truly the best option for you.
