If you’ve been shopping for a massage chair for more than a few minutes, you will have encountered “4D massage chairs.” No, you haven’t wandered into the Twilight Zone!
3D massage chair technology is common in today’s chairs. As you would expect, the D does indeed stand for “dimension.” While a 4D chair does not transport you in time, a well designed 4D can take your mind into space!
To backtrack a bit, the three dimensions in a 3D massage chair are the original two dimensions: up and down and side to side—those have been around for a long time—plus the relatively new introduction, the third dimension: in and out. A 3D chair offers varying massage intensity to provide the depth and intensity (or gentleness) you desire from your chair. You can read more about 3D in our other article which you will find here.
So what do people mean by the fourth dimension in the massage chair industry? Speed. And specifically the up and down rolling speed of the massage mechanism along the chair track. 2D massage chairs and 3D chairs are capable of one constant up and roller speed that has been set by the manufacturer and (due to the design approach taken) can never vary.
The ability to change up and down rolling speeds makes a 4D massage chair perform with even greater sophistication, even more like a human masseuse. The increase in depth and intensity, coupled with variable speed of movement along your back, can — in a well choreographed chair —make you feel you are in the capable hands of a shiatsu master. And as always, a reclining 4D massage chair that offers a True Zero-Gravity® position can make your experience even more relaxing and more therapeutic.
Other features available on the market today, like heated massage or L-track massage, can take your massage experience even further. When you enter the world of 4D technology, you may feel as if you’re traveling into space, and many of our customers report that this is EXACTLY what our selection of 4D chairs do for them!
