What is the difference between center-wheel drive and rear-wheel drive power chairs?

Center-wheel drive chairs, like the Golden’s Compass series, offer users the most intuitive driving by placing the drive wheels directly underneath the user. Center-wheel drive allows the user to turn the power chair in its own space, meaning that whatever the footrest clears, the rear caster wheels will clear when turning in a complete circle. Center-wheel drive chairs are preferable in tight indoor spaces.

Rear-wheel drive chairs have a larger turning radius, meaning you need more space to turn the chair in a complete circle or to navigate tight indoor spaces.
