If you’re new to massage chairs, understanding the terminology helps you get more from your online research or conversations with a Furniture For Life Comfort Consultant. The same is true if you own a massage chair but bought it many years ago—a likely scenario given how well-constructed and reliable these products are—since new features and functions have been developed since then. 

Be warned that massage chair retailers and manufacturers often use these terms differently, which can create a lot of confusion when researching massage chairs, even with a glossary like this in front of you. The surest way to find the best massage chair for you is to try it in-person, then decide how you feel during and after your massage.

That said, below are two groups of definitions used in the massage chair industry. The first has words and phrases essential to understanding how massage chairs function and deliver exceptional experiences. The second has additional terms that are helpful to know as you research your options. 

Essential Massage Chair Terms

2D/3D/4D Massage Chairs:

How a massage mechanism moves affects the types of sessions a massage chair can deliver. There are 2D, 3D, and 4D mechanisms, as well as specialized applications of 4D movement: 

2D Massage Chair: A 2D massage chair mechanism moves in two dimensions: up and down the back and side to side. These chairs deliver basic yet effective massages, adjusting the roller movements to simulate the actions of a massage therapist. While 2D massage chairs are less advanced than 3D or 4D models, they can provide satisfying massages, particularly for users seeking relief in their back and neck areas.

3D Massage Chair: A 3D massage chair has a mechanism that can move in three dimensions: up and down, side to side, and in and out. The chair’s ability to adjust roller depth enables a customizable and potentially more intense massage experience with deeper pressure to targeted areas, mimicking the sensation of a massage therapist applying different levels of force. The result is highly personalized sessions that accommodate intensity preferences and effectively target specific muscle groups.

4D Massage Chair: A 4D massage chair can produce highly lifelike massages with a wide range of sensations thanks to the fourth dimension: variations in roller speed/pace or rhythm. This capability enables the chair to accurately reproduce the nuanced hand and finger movements of a massage therapist. Users experience changes in roller direction, depth, tempo, and pressure throughout sessions tailored to their needs and preferences. 

Sens8™: This 4D massage mechanism is unique to OHCO and uses advanced massage algorithms to mimic the feel of human hands, delivering an exceptional full-body massage experience. Chairs with Sens8™ provide an array of benefits, including stress relief, pain management, and deep relaxation. They offer a range of massage modes, adjustable settings, and a user-friendly interface, allowing for a personalized massage experience. 

Real Pro Ultra 4D Human Intelligence. This is a massage mechanism proprietary to Panasonic massage chairs that locates 1,260 individual points on the neck, back, and buttocks, creating a virtual map to enable correct movements with the right amount of pressure for each part of the body. No other massage mechanism performs a more precise scan or delivers a more customized massage.

Body Scanning and 3D Body Scanning:

Body scanning is a general term that refers to technology that adjusts the massage to the user’s body shape and size. A 3D body scan uses sensors and advanced technology to map the contours of the user’s body, including the back, shoulders, and spine. That information enables the chair to customize the massage experience, identifying areas that need attention and adjusting the position of the rollers and the intensity of the massage accordingly. The result is a personalized and highly effective massage experience. 

ARMS OF EMBRACE™:

This feature unique to the OHCO M-Series offers six independently controlled air cells in each arm that allow for over 479 million unique sequences. It faithfully reproduces the sensation of being gently held or cradled while assisting with bloodflow and lymphatic fluid drainage. 

Artificial Intelligence in Massage Chairs:

At the time of this publication, several massage chair brands claim to include artificial intelligence, but it is unclear if these claims are truthful. In theory, it is advanced technology that enhances the massage experience by learning and adapting to each user’s needs and preferences. The system can analyze user feedback and usage patterns to optimize future sessions automatically, adjusting characteristics like pressure, speed, and focus areas. The objective of AI in massage chairs is to deliver increasingly personalized and effective massage experiences, continually tailoring sessions to the user’s body type, tension areas, and relaxation requirements.

Massage Chair Tracks:

A massage chair’s track is the path available to its massage mechanism as it moves up and down the body. There are several types of tracks:

S-Track: This is a massage track that follows the spine’s curvature and typically stops at the hips. S-Track chairs recline where the chair back meets the seat, enabling the lie-flat position and an exceptional full-body stretch. Users appreciate S-Track massage mechanisms for many reasons, including the fact that they can provide consistent contact and pressure across the full roller range.  

L-Track: This is the term for a massage track that extends from the neck to under the thighs in an “L” shape. An L-Track massage chair’s broad coverage can enable the massaging of areas like the glutes that S-tracks aren’t designed to reach. The shape of an L-track enables the zero gravity position, but does not allow for the lie-flat position and its associated stretch benefits.

SL-Track: This track design combines the broad body coverage of an L-Track and the curved, contour-hugging shape of an S-Track. The result is comprehensive, far-reaching massages and the ability to target specific areas with precision.  Like L-tracks, SL-tracks allow for the zero gravity position, but not the lie-flat position.

J-Track or Flex-Track: These terms refer to a hybrid track that combines the benefits of L-Track and S-Track massage chairs more thoroughly than SL-tracks. Like an L-track or SL-track, these tracks reach from the neck to the glutes or upper hamstrings and allow for the zero gravity position. However, they are also able to achieve the lie-flat position like an S-track and thereby deliver a superior full-body stretch.

MAXTRACK™: This proprietary OHCO M-Series feature provides comprehensive massage from neck to glutes. Designed to move seamlessly from lay-flat position to zero gravity to upright and all positions in between, it provides maximum flexibility and coverage in massage chairs. This feature combines the benefits of S-Track and L-Track systems, ensuring that the rollers maintain contact with the body’s curves and providing optimal pressure even as the chair adjusts to different positions. It delivers massage experiences that are comprehensive and fully customized to the user’s needs and preferences.

Massage Techniques:

Massage chairs (like massage therapists) can deliver different types of massages based on a person’s needs, including deep tissue massage, reflexology, and shiatsu massage.

Deep Tissue Massage: This is a therapeutic massage technique that targets deep layers of muscle and connective tissue to relieve pain, improve range of motion, reduce inflammation, and relieve stress. It’s designed to alleviate chronic muscle tension, improve circulation, and reduce pain by providing slow, firm pressure in targeted areas, particularly the neck, shoulders, back, and legs. This technique replicates the hand movements of a skilled massage therapist and is often recommended for individuals suffering from conditions like sports injuries, repetitive strain injuries, and sciatica. 

Reflexology: This technique targets specific points on the feet to improve health and reduce stress. In reflexology, different foot areas correspond to specific organs and bodily systems. The technique is believed to reduce tension, improve circulation, and support overall wellness. It can also address specific issues like back pain, digestive problems, and headaches by promoting balance and harmony in the body’s energy flow. We incorporate reflexology into our massage chairs through foot rollers and other foot massage features. While it’s focused on the feet and toes, the practice helps release tension throughout the body and promotes overall wellness. 

Shiatsu Massage: This traditional Japanese massage technique uses finger pressure on specific acupoints (also called shiatsu points or pressure points) to alleviate tension and improve circulation. It involves applying rhythmic pressure to acupoints to promote healing, relaxation, and general well-being. The shiatsu massage capability in a massage chair mimics a massage therapist’s use of their fingers, thumbs, palms, and specialized massage tools to exert pressure on the body.

Zero Gravity and True Zero Gravity^®:

Zero gravity is the general term for a reclining position that elevates the legs above the heart, enhancing relaxation and improving wellness in various ways. True Zero Gravity^® is a proprietary feature of Positive Posture massage chairs that is engineered to maximize comfort and health benefits by emulating the shape the body naturally takes in outer space, as discovered by astronauts and studied by NASA.,The position distributes gravitational forces evenly across the body to deliver benefits like enhanced circulation that can help reduce swelling in the legs and improve cardiovascular health, reduced pressure on the spine and joints like the knees and hips that can alleviate pain and discomfort, and improved lung capacity by “opening” the chest for easier and deeper breathing. The weightless sensation also helps relax the muscles and mind, which is good for the body and can reduce feelings of stress and anxiety.
