The Osaki OS-4000T Massage Chair is ergonomically designed with the shape and curvature of the human spine in mind. It provides support of both your neck and back, especially the lumbar area.



The Osaki OS-4000T Massage Chair features quad style rollers with an enhanced massage that feels like the human thumb. The width of the rollers can also be adjusted in order to fit different users frame and accomplish that perfect massage.



The Osaki OS-4000T Massage Chair has the latest technology, it allows for the rollers to map the curvature of the spine with even more accuracy, which makes for a more precise massage that hits all the key areas. Regardless of your body type.



Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This feature improves spinal decompression and decreases muscle tension of the spine. There are 2 stages of zero gravity, the 2nd being more reclined. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.



Located on the bottom of the feet are 2 rows of spinning reflexology massagers which provide a soothing kneading style application. As the rollers spin it will stimulate acupuncture points and as the air bags inflate it will generate a much deeper massage along the bottoms of your feet.



Osaki OS-4000T has re-engineered and developed the next generation of air massage technology, streamlining the air massager to a lower count. Through innovative engineering, we have reduced the total number of air bags but have increased the volume and surface area of massage. By doing so the total number of working valves has drastically reduced from prior model. Which ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs in the market.



Using a durable spandex, the bottom portion of the arm massager features rubber bumps within the four airbags. The airbags compress the tops and bottom of the forearm and hands.



There are multiple air bags along the sides and back of the legs and feet which inflate to apply a compression massage. Located along the bottom foot massager are spinning rollers that apply a concentrated pin-point kneading massage.



In the upper to mid portion of the chair, the air bags are programed to inflate at independent times, which causes the body to twist, creating an enjoyable deep stretch. Stretching is applied to the shoulders, lower back, hips, and thighs.



The Osaki OS-4000T Massage Chair features 5 automatic programs and 3 localized programs. The Automatic Programs are

  • Muscle Relief
  • Thai
  • Stretching
  • Ant-Stress
  • Demo

3 localized programs cover the

  • Back and Lumbar

The intensity and strength of the massage can also be adjusted.


Placed in the lower back region of the chair are 2 heating pads that  help to loosen up muscle tension and enhance the massage experience.



Located in the seat base is a vibration plate that provides a vibration massage to the back of the thighs.


The calf and foot massager is capable of making adjustments according to each individual's leg length ensuring that the massage air bags are concentrating on the correct areas. At the start of the massage, the chair will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your totes down to indicate the chair to stop.



Located on the top right of the main remote you will find a compact wireless remote allowing you to control the main features of the chair without having to struggle to reach the main remote in the reclined position.



The full size Osaki OS-4000T Massage Chair remote presents one of the largest viewing screens to easily visualize what functions the chair has activated. There is also a flip down cover to access the manual functions of the chair.
