2D, 3D and 4D Massage Chairs Explained by Furniture For Life

The world of massage chairs can be confusing, but it doesn't have to be! In this video, Ian Hays of Furniture For Life describes the differences between 2D, 3D, and 4D massage chairs.
2D massage chair mechanisms move only in two dimensions: up/down and side-to-side. 3D massage chairs move in three dimensions: up/down, side-to-side, and in/out. This allows the chairs to provide deeper or lighter massage based on the massage program and the user's preferences. 4D massage mechanisms can change the speed of the roller's motion to more closely mimic the movements of a human massage therapist.
