The Osaki OS-4000XT massage chair with LED light control features an L-Track system with 2 step zero gravity, 6 auto programs, and an Ache Sensor. The Ache Sensor detects the aching point of user's body once the arms are inserted into the sensor naturally in the armrest.

L-Track Massage

As the roller system massages the neck area, it continues through to the lower back and then proceeds to massage the glutes and upper hamstrings.

Full Body Airbag massage

There are multiple airbags located throughout the massage chair to offer a full body massage experience. The 4000XT offers a total of 24 airbags in the massage chair. Airbags are located at the shoulders, arms, feet, and the calf areas. This compression massage helps to continue increasing blood circulation throughout the body to relieve pain and tension.

Unique Foot Roller Massage

OS- 4000XT has one spinning reflexology massage roller located on the bottom of the feet, providing 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.

Two Step Zero Gravity Mode

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.

Extendable Footrest

OS-4000XT has an extendable footrest which can be extended up to 6.5 inches.

Six Auto Massage Program

The OS-4000XT has 6 different auto massage programs. Neck/Shoulder, Strengthen, Relax, Thai, Recover and Sleeping.

Six Massage Style

The Osaki OS- 4000XT massage chair comes with a manual mode so you can pinpoint a desired massage for a specific area on your body. OS-4000XT can perform Kneading, Tapping, Swedish, Clapping, Rolling and Shiatsu. You can either pinpoint a specific spot on your back for the massage or massage by sections of the body.

Manual Massage Setting

You can meet variety of options to customize your massage with the OS-4000XT. OS-4000XT has a Manual Control Function for Mode, Massage Position, Massage strength and width of the Rollers.

 Space Saving Technology

Osaki's innovative design team has engineered a space  saving technology that slides the chair forward as the chair reclines. As a result, the OS-4000XT takes only 2 inches to get to the fully reclined position.

Built in Bluetooth Speaker

The Osaki OS-4000XT is equipped with Bluetooth technology that allows the user to listen to their favorite music on high quality speakers in the headrest. 4000XT is featured with a 4D surround sound system which has four speakers located in the headrest and side panel areas.
