Regular use of a massage chair can actually improve and eliminate many common health problems, ease pain and swelling, improve your immune system, and increase levels of neurotransmitters that assist in reducing depression.

Relaxing the body and mind is crucial to our overall well-being and the cumulative effects of regular massage will strengthen and tone the entire body, prevent strains and injuries that may occur as a result of increased pressure and tension.

With a wireless remote, you can select various massage techniques, target areas that need the most attention, or all major parts of the body. The OS-4000 boasts 48-airbags that cover the Shoulders, Neck, Hip, Arm, Lower Back, Calves, and even Feet, and for those of you who prefer a more customized program, this massage chair is equipped with a computer body scan for the back and legs that will help you create an individual plan to maximize your massage experience.

Advanced Features

Deluxe Zero Gravity – Zero gravity positioning relieves stress on the body and allows for a deeper massage experience. This position will relax and decompress your spine, distribute your weight across the chair as the rollers ease away tension and stress. You will experience a more invigorating and effective massage.

Zero gravity positioning provides you with tremendous health benefits:

  1. Relaxation of the Neck and Back. By elevating the legs above the heart at a 130—degree angle, pressure is relieved off of the spine and spread across your entire body.
  2. Increase Lung Function. In a reclining position, our lungs are fully able to expand which means less pressure on the diaphragm.
  3. Increased circulation. Sitting or reclining in a massage chair will relieve neck strain, increase energy flow in blood and increase your energy throughout the day.

Newly Added Foot Rollers extend your kneading massage all the way down to the soles of your feet, and give you the added benefits that reflexology has to offer in an already outstanding massage chair.

Ergonomic S-Track movable intelligent massage robot – The massage track will automatically detect your body curve, adjust to your shape and size automatically and it will provide you with a special focus on areas such as the neck, shoulders, and lumbar area.

Six Unique Auto Programs: With six pre-set programs to choose from you are certain to find a program that is suitable to your needs and preferences. Choose from: Healthcare, Relax, Therapy, Smart, Circulation, and Demo.

3 Manual Massage Modes: For the upper body, there are 3 options available: Full body, Partial, and Fixed Modes.
