    Osaki OS-4000 Banner

    The OS-4000 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.

    Colors: Taupe, Brown, Black
    Computer Body Scan System


    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.

    Ergonomic S-Track Massage


    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.

    2 Stage Zero Gravity


    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 also reduces the vertical stress on the spine. There are 2 stages of zero gravity, the 2nd being more reclined. Study show that when the legs are at or above heart level, it promotes better circulation.

    41 Airbags Air Massage & Back Heating


    Next Generation Air Massage Technology

    The airbag massagers have been upgraded and engineered, reducing the number of airbags and valves but at the same time increasing the surface coverage. Less power is consumed and runs more quietly with the reduction of air pumps and valves, allowing for a more tranquil massage experience. The material used to create the air bags have also been modified with industrial grade material for durability, yet soft and pliable to provide comfort and consistency.

    Lower Back 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.

    Easy to use LCD display remote
    Easy to use 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.

    Auto Extendable Footrest

    Auto Leg Scan

    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.
