          Osaki OS-4000T Massage Chair Strack

          True Ergonomic S-Track

          The OS-4000 Zero Gravity massage chair is ergonomically designed to contour various 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 consistent massage pressure and 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 Massage Chair Body Scan

          Computer Body Scan System

          Equipped with the latest technology, the rollers can map the back curvature more accurately, translating into a more precise massage hitting all the key areas. This highly advanced chair will self-adjust regardless of body type, making each massage experience feel customized.

          Osaki OS-4000T Massage Chair Foot Rollers

          Unique Foot Roller

          On the bottom of the feet are two rows of spinning reflexology massagers that provide a soothing kneading style application. As the rollers spin, it will stimulate acupuncture points, and as the airbags inflate, it will generate a much deeper massage along your feet.

          Osaki OS-4000T Massage Chair Airbag Massage

          Next Generation Air Massage Technology

          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 airbags but have increased the volume and surface area of massage. By doing so, the total number of working valves has drastically reduced from the prior model. This ultimately puts less stress on the chair, making it one of the most mechanically sound massage chairs on the market.

          Osaki OS-4000T Massage Chair Auto Recline

          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 Massage Chair 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 chair's main features without struggling to reach the main remote in the reclined position.

          Osaki OS-4000T Massage Chair Heat Therapy

          Lower Back Heat Therapy

          There are two heating pads on each side in the lower lumbar area. Heat therapy is an excellent compliment to roller and airbag massage. The heating pad is not intended to be used for more than 30 minutes a day or the duration of a preset massage program.

          Osaki OS-4000T Massage Chair Leg Scan

          Auto Leg Scan

          The calf and foot massager can adjust each individual's leg length, ensuring that the massage airbags concentrate 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 Massage Chair Seat vibration
