So what do 2D, 3D, and 4D mean in massage chairs? Let’s first start by defining the technology. 2D, 3D, and 4D refer to the type of roller mechanism attached to a roller track that travels up and down, massaging the user’s back.

All massage chairs can fit into one of these three categories depending on the sophistication of the roller. Let’s take a look at each type.

What is 2D Roller Technology?

A 2D roller is the most basic type of roller mechanism and consists of a roller mechanism that can travel up/down the roller track. You can control the strength of the roller, usually up to 5 levels, by adjusting it for either a slower, lighter massage or a faster, more aggressive massage. You can adjust the width on some models, but this is limited to only programs that utilize the rolling technique.

What is 3D Roller Technology?

A 3D roller has all the same features as a 2D roller but is a step up and offers more depth adjustment. What does this mean? The 3D roller extends out from the roller track about 3″ to apply a deeper or lighter massage; this is where it gets the 3D name.

What is 4D Roller Technology?

A 4D roller would be considered the most advanced technology of all roller tracks. The 4D roller can perform all the movements of the 3D roller, but it adds an automatic speed adjustment that makes the massage feel more humanistic. The roller automatically speeds up and slows down, emulating the fluid movement of human hands. The 4D roller is the most sophisticated technology and is primarily used in only top-of-the-line models.

What is the Best Type of Roller Technology?

Honestly, you can find an excellent model with all the different roller types. It matters what you’re looking to get out of a massage chair. The 2D models are perfect for getting the everyday benefits of massage, but if you need something more targeted for pain relief, then a 3D and 4D model may be better suited for you.
