Osaki OS-4D Pro JP Japan Premium Massage Chair Refurbished

So what is 4D? Traditional massage chairs move on a 2 plain axis, up & down and side to side. Prior to 4D technology there was 3D which added an addition dimension by allowing the roller heads to protrude in and out, resulting in an increased or decreased intensity of the back roller massage. With 4D the massage heads will move in out depending on the massage.
