Front suspension is designed to dissipate road vibration so that it does not enter the frame of the chair and transfer it to the rider. It must also absorb the higher impact energy created when the front caster wheels encounter obstructions while rolling over every day surfaces.

A study conducted by the Department of Health & Human Performance, Iowa State University determined that 80% of all the vibration within the frame of a wheelchair originates from the front casters. Their studies showed that 76% of all the vibration in the frame of the chair is eliminated by the addition of (Frog Legs) front suspension.
