The 2D massage technique uses rollers that move up and down, from the neck to the trunk to the lower back. This technology is good for physical and mental health, but 3D technology takes it one step further. The rollers of the 3D massage chair can go up, down, left and right, in and out, and can be pressed into the back, just like a massager would. Since the rollers are able to push in and out, the intensity of the massage can be adjusted. This makes the 3D massage chair ideal for families with multiple users with varying intensity preferences.
