Features and Programs


SL Roller Track

The rollers of a massage chair ride on a track which is what determines the distance to which the rollers will travel. 

Osaki Pro Aster has the SL track formation, this track formation is a combination of the S- track and the L-track formation.

Each of these types of tracks has its advantages. 

The S-track formation is designed to tightly fit the spine so that it mimics the sinusoidal curvature of the back. 

It runs from the shoulders down to the waist region.

This means that when a massage chair has an S-track design, the massage rollers will stop its massage at the waist region. 

The L-track formation, however, has more distance to cover, it not only goes from the shoulders to the waist but extends to the hamstrings. (Underneath your buttocks).

The difference between the two tracks is mainly the distance covered and the slight not so noticeable difference is the mimic feature of the S-track which the L-track does not have.

Osaki pro-Aster decided to combine the two features, so your track starts with the S- track from the shoulders and then continues as an L-track down to the buttocks area.

The most important feature of this SL track formation is providing a thorough massage to the hamstrings.

SL track formation covers 50% more surface areas than S-track alone.

The rollers used by this massage chair is the 2D rollers. 

They are designed to move forward and backward along the tracks, they can also move sideways laterally.

The higher the dimension of your rollers the more effective massage it can offer.

 Top 7 Osaki Chairs On Market


The Osaki OS-Pro Aster is equipped with the ability to recline the chair to achieve a zero-gravity position. 

The zero-gravity position is the best position to assume during a massage. 

This is because the back region is decompressed and is completely supported by the backrest. In this position, there is an increase in blood flow in the body and toxins are easily flushed out of the system.

Zero-gravity helps you to enjoy your massage thoroughly.


Full Air Massage

Osaki OS-Pro Aster has a very small number of airbags but they provide adequate massage functions where the massage rollers cannot reach. 

The airbags are18 in number, though they are few, they are quite effective and energy-efficient.

The airbags were re-engineered with multilateral layers and more surface area to provide effective massage with fewer airbags.

With fewer airbags, the wear and tear occasioned by the air pump valves are reduced. 

The airbags are located at the shoulders, arms, upper arms, calves and feet and hands.

The airbags inflate and deflate to provide pressure which is used to stretch, twist and impact on the muscles.




Foot massage is one component in a massage chair you should not joke with, especially if you suffer from tired feet. 

The Osaki OS-Pro Aster is equipped with double spinning rollers underneath the foot of the massage chair.

These rollers spin in different directions to provide pressure which is applied to the different acupressure points underneath the feet.

The rollers are helped by the airbags that press the feet down to ensure maximum impact.

The rollers provide a kneading style massage on the feet. 


LCD Remote

Osaki OS-Pro Aster has a slim LCD remote that is easy to use, the texts are clearly typed and you can see what function you are currently using. 

The Remote is attached to the chair and can easily slide into its holder. 

You can operate different functions independently.
