Zero Gravity

When the zero gravity mode begins, there is an elevation angle of about 118 degrees between the body and the feet. The position of the thigh and calf is greater than the position of the heart. The gravity of each body part will be evenly distributed over the massage chair, to fully help release the pressure from your body. It offers you a state of weightlessness, to help you enjoy the perfect relaxation without any restrictions.

Zero Space

Designed with a single button to switch smoothly and with a unique forward slip, the fully open massage chair can be at a distance of just 5 cm from the nearest wall. In the process of achieving 22 cm function at the front, the seat will slide forward, giving up the position of the traditional massage chair, limited by the space available between the chair and the wall behind it. When the seat is reclining, you may feel a feeling of flutter.


Ergonomics combines with a studied and super long curved rail technology an “L” shaped space to increase the massage distance to 135 cm, allowing you to enjoy a personalized massage from head to toe, helping to maintain the vertebrae of the human body in an “S” shaped curve, which will achieve relaxation of the spine, relieving tense muscles.


Emulating the touch of the human hand using advanced rolling technology, the chair can offer a Guasha massage as a professional masseur. With a 3 cm travel, the massage focuses on the Yongquan point in the soles of the foot, either by a gentle and stable massage or a gradually stronger massage, which can bring comfort and unparalleled pleasure.


Airbags of different shapes pack completely calf, ankle and foot to bring you a triple pleasure. The compression, the pause, and the method of release of air pressure, which stimulates acupuncture points Xuanzong and Taixi, can bring you perfect comfort and harmony.


Magnetic therapy with 8 precisely positioned permanent 300CC magnets can improve low levels of magnetite in the body by stimulating Chengzhang and Zanmai acupuncture points on the calf.


Intelligent mechanical hands can move up and down the neck, shoulders, back and waist. They can automatically induce the human curve and the range can be as wide as 21 cm; the vertical road is 135 cm, which completely covers the human back.


The “S” shaped curve supporting the body is a combination of the back massage structure combined with human engineering principles, so as to offer you a massage precisely positioned behind. The width can be adjusted from 6 to 21 cm, with three options.


Equipped with 12 airbags according to the curve of the human arm to perform an all-round massage on the Yangtze and Quichi points on the arms. Balanced three-dimensional traction from inflated airbags will relax and refresh you from arm to palm.


The feedback function of heating 0ºC-50ºC can relieve coldness and pain in the back. The wavelength of the far-infrared emissive coincides with the wavelength of the human body, so that energy can be absorbed by the human cell, which can activate cells and stimulate metabolism.
