But what does that mean? As explained by most massage chair companies, the term 4D generally refers to the ability of the chair to vary the speed of the rollers. True 4D, on the other hand, is a 3D massage chair that is also an L-Track or an armchair that can massage the back and buttocks. So the fourth “D” is to press on the buttocks and hamstrings. These chairs are quite rare, since the technology is new and some don't work very well, but the Positive Posture Brio is the best there is.
Technically, they should be called “3D L-Track”, but 4D sounds better. Apart from that, 3D massage chairs allow you to adjust the intensity of the massage according to your needs and preferences. When looking for a suitable massage chair, you will find the terms 2D, 3D and 4D massage chairs. If you have the budget for a 4D chair and are going to use it regularly to treat very tense muscles, it may be worth investing in them.
Core Cirrus, one of the most intense massage chairs on the market, doesn't look like 4D, but it offers very deep tissue massage. Even for us, who spend hours analyzing several massage chairs, it's difficult to verbally describe how each chair feels. The goal was to make the 4D massage chair much more capable of reproducing a massage that a therapist can provide. The body scanning capability of 3D armchairs (ability to determine their shape, size and height) is also much more precise and precise than scanning in a 2D massage chair.
An occasional user or someone not looking for an exceptionally deep massage will likely enjoy a massage chair that offers a 2D system. You can adjust the intensity so that the massage is as intense or gentle as you want, with some limitations based on the chair itself. This means that users can customize their massage sessions without problems, and this is possible thanks to the variety of strength settings offered by these massage chairs. One of the first things to consider when thinking about a massage chair is what type of roller you want.
These are probably the most expensive massage chairs on the market, but their price is justified considering the relief they offer. So you could say that there is no such thing as a “4D” massage chair, or that all 3D massage chairs are also 4D.
