Quantum Edge® 3
The established mid-wheel workhorse, with the widest electronics choice.
Overview
About the Edge 3
The Edge 3 remains one of the most widely prescribed Group 3 bases in the country. A 20.5" turning radius makes it manageable in tight domestic spaces, and it supports the broadest range of Q-Logic electronics in the Quantum line — which matters when a patient drives with an alternative control rather than a standard joystick.
Who it suits
- Tight indoor environments — apartments, older homes, narrow hallways
- Patients using alternative drive controls such as head array or sip-and-puff
- Anyone needing iLevel elevation on a proven, widely serviced platform
