4D massage chair zero gravity
4D massage chairs do everything that 3D massage chairs do in terms of motion. The rollers will also go up and down, side to side and back and forth. 4D takes this a step further, by adding a 4th dimension to its massage movement technology which is that it also adjusts speed. With guidance from professional holistic massage therapists, 4D massage movements were crafted to add variations of speed to each style of massage. Much like the time-tested traditions of Japanese massage, the hands of the masseurs slow down or speed up, even pause to apply attention and pressure to tight muscles, into the areas of your back that need it the most.
