The OS-4000T massage chair features beautifully updated upholstery and includes Zero Gravity, a 30 inch Roller Stroke, Body Scan Technology, S-Track Massage Robot, full body air massage, seat vibration, and heat therapy for your back.


Osaki OS-4000T - S-Track


The OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety of spine shapes. The Spine curvature is unique from one individual to the next. The S-track system allows the roller heads to massage along the back from the neck down to the lower spine with a consistent pressure in the massage, along with a comfortable support. The typical massage tracks, being linear, create an inconsistency in pressure applying weak massages in the neck and lower back.


Osaki OS-4000T - Intelligent Body Scanning

Intelligent Body Scanning

Equipped with the latest technology, it allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized.


Osaki OS-4000T - Specialized Foot Massage

Specialized Foot Massage

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 - Air Compression

Air Compression

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.


Osaki OS-4000T - Auto Recline and Leg Extension

Auto Recline and Leg Extension

This chair defines luxury. Fully automatic to make every movement effortless. The simple to use remote control allows you to operate the foot extension, leg rest, recline of backrest, and the zero gravity position.


Osaki OS-4000T - Wireless Controller

Wireless Controller

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.


Osaki OS-4000T - Lumbar Heat Therapy

Lumbar Heat Therapy

There are 2 heating pads, one on each side in the lower lumbar area. The heat therapy is a great compliment to roller and airbag massage. The heating pad is not intended to be use for more than 30 minutes a day or the duration of a massage preset program.


Osaki OS-4000T - Automatic Extendable Footrest

Automatic Extendable Footrest

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 legs will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your toes down to indicate the chair to stop.


Osaki OS-4000T - Vibrating Seat

Vibrating Seat

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