Single Motor Chairs – This is where only one motor controls all of the electric functions on a chair. These functions are the backrest, footrest and riser; these functions can all be operated from a single set of buttons but will have limited flexibility on positions.
Dual motor chairs – This is where there are two separate motors in the riser recliner chair. With the dual motor chairs, one motor controls the backrest while the other motor controls the footrest and rise function. This allows you to have complete flexibility on where you want the footrest and backrest to be positioned.
