Features and Programs

4D Roller Design

The rollers on a massage chair are what determines how effective a massage chair will be. 

The rollers are what is akin to the human thumb used for massage.

 Osaki OS-4S JP Premium has one of the humanistic roller designs there is. 

The 4D rollers are designed to move, vertically, horizontally, in and out and then at a variety of speeds to create the 4th dimension.

This actually mimics the Japanese style of massage which deploys varying speeds to carry out the massage.

There are not many chairs in the market that deploy a 4D massage.

 Osaki OS-4S JP Premium is revolutionary in deploying this mechanism.

Body Scan Technology

Osaki OS-4S JP Premium uses computer body scan technology which maps out all the contours of your body in other to better understand where your acupressure points are located. This scanning method is what enables the chair to accommodate different body types and heights. 

The chair is intelligent in using this technology so it does not assign a one size fits all type of massage.

The Body scan technology in Osaki OS-4S JP Premium is double sensing, meaning it is able to accurately detect your spinal line and your shoulder length. 

This ensures a more accurate massage.

Full body Air Massage

Osaki OS-4S JP Premium presents its full-body massage system with a multi-layered airbag system that is fewer in number but covers much surface area.

With the reduced number of airbags, the chair will last longer and avoid wear and tear that results from the pumps and valves of the airbags.

Airbags are used to massage areas that the rollers in a massage chair cannot reach.

The airbags are located at the following positions

Outer Shoulder: These airbags are attached at the upper sides of the backrest, they inflate and deflate to create pressure that is used to massage your outer shoulder.

It can also serve as a grip to hold you in place while the rollers deepen their massage on your back.

Hand and Arm Massage: The airbags create pressure which is used to massage the hands and the arms. The pressure also ensures that the arms are held in place while the massage is taking place.

Hip Massage: As the airbags inflate, it creates pressure which squeezes the waist to make an impact on the hip muscles. 

This helps to relieve pain and stress.

Calf and foot massage: Osaki OS-4S JP Premium also uses airbags at the feet to massage the calves and the feet. The pressure presses down on the foot, while the back airbags also press on the calves to create a pressure effect that is so enjoyable.

Heat Therapy

Osaki OS-4S JP Premium deploys heat at both the backrest and the feet. 

The heat helps to loosen the muscles for a deeper and more effective massage. 

Most chairs only offer heat therapy at the lumbar region but the Osaki OS-4S JP Premium made a huge difference by also offering heat at the feet.
