Description

The 4Front 2 HD brings the 4Front platform’s front-wheel drive handling to riders who need a 450 lb weight capacity without giving up complex rehab options. Reinforced caster arms and robust 4-pole motors back up the higher rating, while Smart Traction Control and Smooth Ride Suspension smooth out obstacle transitions at speeds up to 5 mph.

Despite its heavy-duty build, the base keeps a 24-inch width and a tight 24.5-inch turning radius, so it remains practical in hallways and doorways. An optional 10-inch power seat lift (rated to 400 lbs) allows driving at 2.7 mph while elevated, and the chair pairs with TRU-Balance 3 HD power positioning and Q-Logic 3e electronics.
