They do this by inflating and deflating air bags in a variety of methods and speeds, essentially compressing and manipulating the muscles and connective tissues. The air cushions can work independently or in combination.

The L-rail - also known as the L-track - allows the massage rollers to begin massaging on the underside of the head, then move down the back (as with the S-shaped S-rail), wrap themselves under the gluteal muscle and then to the Hike back of thighs. This is the extension of the S-rail as the rollers now also reach the buttocks and thighs.

Air ionizer:

Some massage chairs have an airflow function that blows a breath of fresh and purified air towards the user. The air ionizer cleans the air with the help of ions. These are extremely suitable as dust collectors. The charged particles combine with dust and other air particles and thus become larger particles. Due to their increased weight, these trickle to the floor, which frees the room air from potential pollutants.

Massage chairs have integrated motors that take on various functions in the chair. There are rotary motors, piston motors and vibration motors. Rotary motors control the massage rollers as well as the kneading and tapping functions. Piston motors control the functions of the legrest and backrest, and vibration motors control the vibratory movements.


The leg member of the massage chair in which the calf and foot massage device is installed is called an ottoman. Some models have a function with which the ottoman can be hidden, retracted or adjusted. In this way, the furniture looks less like a therapy chair and more like a designer living room chair.

heat therapy:

Devices with an integrated heat therapy function have a number of built-in heating coils that warm the body, loosen it and prepare it for massage therapy. They are usually placed on the upper and lower back, as well as on the feet.

Zero Gravity:

Massage chairs with this function - also called Zero-G or weightlessness - convey a feeling of weightlessness for the user, as the person being massaged lies in a position in which the knees are slightly above the heart. Thanks to the body weight, the body presses itself even more firmly into the armchair and enables a deeper massage.

I would like to buy the ZERO GRAVITY A90 premium massage chair for my mother, who is 350 years old.
Now I want to know if the operation is uncomplicated? If there is a user manual in German, the voice control is German and can be switched off.

With kind regards,
Steffen Mueller
