See how our chairs stack up against each other

If you find yourself lost in a sea of terminology, you're not alone. Understanding the inner workings of a massage chair can be confusing. We're here to help explain the main elements that will ultimately provide the relief and knowledge you are looking for.

So, what are 2D, 3D, and 4D? What does it all mean?

By now, you would have probably formed an impression of how each works in terms of its dimensions and how it conforms to the individual's body. Since the inception of therapeutic chair design, 2D design is known as the standard. With the advancement of roller technology, the quality of massage offered in the 3D chairs improved to give clients a more encompassing experience. As the newest member of the massage chair family, the 4D model offers results that are comparable to the work of a professional masseur.

2D Massage Chairs

Two-dimensional chairs have rollers that move in only two directions. They move forward and backward, as well as side to side. In conjunction with the zero gravity feature found in most high-quality chairs, this is an excellent choice for relieving back pain and soothing sore muscles.

3D Massage Chairs

3D technologies take the already solid experience found in 2D chairs a step further by allowing roller heads to be moved outward for a deeper massage. You can adjust the intensity of the protrusion from the track at your convenience as it is all controlled from the palm of your hand. The result is a wonderfully relaxing and rejuvenating experience.

4D Massage Chairs

With a good understanding of 2D and 3D, what makes 4D so different? Its unique 4D design further offers a human-like experience, focusing and mimicking the movements of Japanese massage therapists. Control of the rhythm and depth makes the rollers accelerate and slow down at varying intervals to focus attention where it is most needed.


As a 3D chair will, these chairs also move from left to right, up and down, as well as in and out, but their touch and reach are softer and more thorough. In effect, it is like having a personal masseuse treating you to a relaxing, tactile euphoria.


So how does that work? The 4D chair offers a relatively new track design that pushes and works into the lower back, glutes, and hamstrings creating a full body massage. Combined with podiatry features and heat, this is the most toe-curling pleasure yet.

What are Roller Tracks?

Most massage chairs have long roller tracks that start from the head and move down to the lower back. More recently in the 4D design mentioned above, they even go down to the glutes and hamstrings. These rollers' jobs are to do most of the massage tasks in therapeutic chairs that operate mechanically. The area most commonly focused is the spinal region of the body.


The rollers that travel along the track move in a vertical and a lateral direction to mimic the touch of a human massage specialist. This makes tapping and kneading possible. At the same time, there are a number of roller tracks that allow backward and forward movement. These are known as 3D roller massagers.


As far as the shape of the track is concerned, there are two types. These include the S-track and the L-track.


Among the three types of massage chairs, we have already discussed the S-track, the L-track, and the SL-track. Let's compare their features.


These tracking systems differ primarily in shape. For example, S-Track will give you a message in the shape of an S. And L-Track will provide you with a massage in the shape of an L. While SL-track roller chairs come in an L shape, they may not offer the same quality of massage as the L-track chairs.


From the hindhead to the lumbar region, the massage area of the S-track massage chair extends. On the other hand, the massage area of the L-track massage chair is from the head to the buttocks area.

S-Track 

Modern massage chairs follow the curvature of the human spine and are so-called, S-track chairs. The rollers follow the natural curvature of the spine by moving up and down the S-track's sinusoidal shape. Initially, the roller moves forward at the top of the neck until it reaches the mid-back, at which point it retracts a bit before moving forward again. Users are thus provided with a comfortable and natural massage experience.


Roller tracks are not designed as straight lines because the spine is naturally curved. The back and neck would get strained rather than relaxing if there was only one straight line along the roller tracks. It is unfortunate that the first massage chairs were designed with straight rather than curved rollers.

SL-Track 

L track as well as SL system: What is the origin? This idea is right most of the time, but not always. Although the SL tracks use a L shape, they are generally straight without any curves. The use of such devices is low since they do not perform well in terms of massage therapy. Even after there are more exceptions than the SL-Track rule, they are still present.


It is crucial to ensure you are not buying an old straight-track massage chair before purchasing an SL-track chair since it is usually more expensive than S-track or L-track chairs.

L-Track 

A few years ago, a prototype of the L-track roller chair was displayed in Las Vegas, containing rollers that went under the seat. The chairs are relatively new. Despite not having the title of an 'L-track' roller, the prototype quickly acquired the name due to the path it followed.


Later, the first similar model formally with the title of ‘L-track’ hit the market not so long ago. As a result of this new technology, everyone had their attention drawn towards it especially in the shopping malls and public areas.  Since then, there have been several more models and brands of ‘L-track’ rollers. Personally, we believe that the L-track is a great step forward in the world of massage chairs within a decade.

In formal terms, the L-track roller is also referred to as the extended roller track. It is simply an extension of S-track rollers with an added path that goes below the lower back and reaches down to the buttocks and hamstrings. In other words, the L-track continuously moves from the head down to the hamstrings which generate the sensation of a full body massage.


It is quite impressive that previously, the seat only used to include airbags for massage. Today, however, you've got a full body massage within a seat that reaches down to the hamstrings. On top of that, many massage chair models have sections for a foot massage which can be very enjoyable especially with heat.


If you have been suffering from sore buttock or hamstring muscles, the L-track massage chair can be a very beneficial addition to your living room. This can be especially beneficial for those who suffer from sciatica near the pelvic muscles or conditions such as the piriformis syndrome. 

Which one is best?

You may be interested to know which of the roller tracks is the best. So far, we have discussed S-Track, L-Track, and SL-Track in detail. Now find out which system is better. We will search based on the expansion of the L-track and S-track = SL-track system.


So far, we have a clear winner in this regard due to great coverage, and that is the L-track roller massage chair. A massage chair with an l-track will give you a message in a wide coverage area. It will provide good massage support in the most problematic places in your head to your buttocks.


If you have sciatica or piriformis syndrome problem that affects your lower body, L-Track is best for you. Because as we said before, these roller massager chairs offer you massage in the range of expansion.


If you are prone to allocation in a chair for the long-term, L-track rollers will be perfect for you. Because L-track massage chairs are the best chairs for lower back and hip pain that massage the glutes. Long time use of these chairs will not have any side effect on your body.

Due to the significant features provided, we have considered L-Track as the best roller massagers chair. Even a few features are better than 3D rollers and mechanical rollers, and it is impressive. And You can choose the L track to help your lower back, particularly the hamstrings or glutes.
