When shopping for a massage chair, you’ll probably come up against quite a few new terms.. Do you want zero gravity? Should you get an S-Track or an L-Track? What’s the benefit of a heated chair? It can feel like you have to learn a whole new language, as the options are seemingly endless!

No worries, we’ll break it all down. One of the important terms you’ll want to pay attention to is the massage chair roller type. More specifically, whether a chair has a 2D, 3D or 4D one. So what exactly is the difference between a 2D, 3D and 4D roller?  

Essentially, they’re the difference between a light massage and a deep one. You can think of these as depths (that’s the “D” after the numbers) the rollers push into the body. The basic concept is, the higher the number, the stronger the massage can generate by pressing into the body at a further depth. 

Is that nice, deep massage what you’re after? Here are a couple of the best 4D Roller Chairs we recommend!
