2D, 3D, 4D, 5D in massage chairs – vlog #25

vlog #25 EN

Until now, technologies involving operation in several dimensions have been associated mainly with TVs or cinema screenings. However, as it turns out, this technology has also found application in massage chairs. In the next episode of our vlog about massage chairs we present what massage looks like with 2D, 3D, 4D and 5D technologies. Paweł explains in detail all the differences between the individual dimensions, and how the massaging arms move in each of them, as well as how this affects your experience in the massage chair.

So if you’re thinking about a massage chair and wondering whether to opt for the 2D, 3D or 5D massage, get in touch with us. And if you haven’t already watched the other episodes we’ve filmed, you can find them under the VLOG category. 


– Paweł, while browsing massage chairs online at restlords.com, I noticed the terms “2D”, “3D”, “5D”. Could you elaborate a little bit more on that?

– This technology may be initially associated with televisions, screens. However, it’s also found in massage chairs. But, let’s start from the beginning: 2D technology. Every massage chair has massaging arms on linear guides. At the tip of my fingers and at the end of these massaging arms there are massaging balls. The arms operate along the line of the spine. If they work up and down and sideways, like this, then it’s 2D technology. Meaning two dimensions: up-down – one dimension and right-left – the other. Of course, this is accompanied by a corresponding system of springs, where the arms press along the line of the spine. However, it operates in these two dimensions.

If we move on to 3D technology, i.e. add another dimension, we’re talking about movement that’s not only up and down, right and left, but also closer and further away from the line of the spine. It can go away a little bit in the chest section and be closer in the lumbar area. It’s possible thanks to scanning, i.e. the chair adjusts itself by scanning the line of your spine. The third dimension allows you to adjust the intensity yourself. By bringing the massager closer to our body, we can increase the pressure on the muscles along the spine. Both scanning and manual adjustment make the third dimension an interesting feature, increasing the quality and accuracy of the massage. Meanwhile, going further, there comes 4D.

Roughly 5-6 years ago, Fujiiryoki released the massage chair that featured 4D massage, and the thing that was added in the form of the fourth letter ‘D’ is about the speed of the movement, and in fact its consistency or lack of it. When we get massaged manually, the movement of the human hand is more of an acceleration-slowing down, it’s not consistent. And so the 4D makes these massaging heads accelerate and decelerate at just the right moments, giving the effect of a smoother, more hand-like massage. This has obviously added to the experience. I’m not going into how the technology evolves in other companies, but in Fujiiryoki, the fourth dimension made all the difference.

Moving on, we have the 5D. Again, introduced by Fujiiryoki. Technology with artificial intelligence. There were algorithms to control the massage chair’s performance. What does that involve? Well, the massaging arms of the chair are able to determine what the stiffness of the muscles along the line of the spine is in real time, how tense or relaxed the muscle is. Using this data, it is able to adjust the desired intensity of the massage. If the chair senses that the resistance of the muscle in the lumbar area is higher, it’s stiffer, then it goes for a more intensive massage. If the resistance is lower, the massage becomes more shallow.

So step by step, we’re getting closer and closer to human manual massage going from 2D to 5D. We mimic the movement of the human hand. These are the differences.
