"Mid Wheel Drive Power chairs, look very different from rear wheel drive power chairs, as the main drive wheels have been moved from the rear of the wheelchair to the middle part of the wheelchair.
Moving the drive wheels to the middle of a wheelchair makes a very big difference to how the wheelchair drives and the space the wheelchair needs for turning. Mid Wheel Drive Power chairs also have a very low centre of gravity, which can make them feel more stable in use.
Like rear wheel drive power chairs, mid wheel drive power chairs are controlled in just the same way, with a joystick control, which can be mounted on either the left of right of the power chair. Because mid wheel drive wheelchairs need less space to turn in, you can very often get a larger wheelchair into a smaller space."
