Dual Motor Tilt in Space Riser Recliners. Dual motor riser recliners have the advantage over single motor chairs of being able to independently operate the backrest recline and the legrest elevation as the 2 motors work independently for each function. When reclined the tilt in space function allows the fixed back and seat to move with one another, promoting better posture.
