3D Roller Technology - Massage Chairs

3D chairs run on the X,Y and Z axes. This provides the 3rd dimension of movement so you have up & down, side to side and in & out movements. When you see the term 4D this means the 3D mechanism moves are varying speeds to truly mimic the motions of a human massage. The third dimension of in & out also allows the user to change the level of intensity.
Turn up the 3D and the rollers are able to push out further, deeper into your back. This means a 3D/4D massage chair grows with you over time as your body becomes accustomed to deep tissue massage and craves deeper intensity. You can adjust the intensity level of the rollers from very gentle to deep tissue. 3D/4D massage chairs are great for homes with multiple users, since everyone can easily find the perfect intensity level for their personal preference.
