Available at AppliancesConnection


    L-Track Massage
    The L-Track system massages from the neck, past the glutes, and down to the back portion of the thighs. The track in which the massage heads move is curved to contour the back and glutes area.

    Space Saving Recline Technology
    Most typical massage chairs consume a lot of space, especially when in the recline position. Massage chairs require up to 3 feet behind the backrest in order for the chair to fully recline. Osaki’s innovative design team has engineered a space saving technology that slides the chair forward as the chair reclines. Less than 4 inches of space is required when laying back!

    Lumbar Heating Pad
    On each side of the lower lumbar area are individual heating pads. The heat therapy is a great compliment to roller and airbag massage. Heating the body’s temperature is known increase blood circulation and loosen tense muscles. The heating pad is not intended to exceed more than 30 minutes of usage a day.

    Zero Gravity Positioning
    Inspired by NASA, the Zero gravity position is a great way to enjoy a massage. It positions the spine so that it reduces the vertical pressure. In the zero gravity position, the weight of your back is virtually supported by the backrest which also maximizes the intensity of the massage.

    6 Massage Techniques
    The Osaki OS-4000 CS has 6 unique massage styles: Kneading, Tapping, Rolling, Shiatsu, Kneading & Tapping and Kneading & Shiatsu. For the user’s convenience there are 6 pre-set programs to select from, each one goes through all the different massage styles. Each pre-set program is unique because it will focus more one particular massage than the other.

    24 Airbag Massage
    Osaki strives to make its chairs efficient and extremely reliable. Other brands of chairs will market to have 70+ airbags for the full body massage. The engineers believe with more airbags and more valves, the more strain the air pump endures. With more moving parts, the greater the chance of something failing. Osaki has been engineering its chairs to reduce the airbag count and at the same time increasing the surface area by using more pliable and durable material which have received great feedback. All 24 airbags are strategically placed to optimize the squeezing effect of the shoulders, arms, hands, hips, calves and feet.

    Adjustable Outer Shoulder Massage
    Osaki has taken custom fitting to a whole new level by adding adjustable outer shoulders. The outer massage airbags are typically stationary and depending on the height and width of the user, the shoulder massagers are at times very ineffective because of positioning. With the ability to adjust to 3 different widths, the user has the ability to improve the strength and fitting of the outer shoulder massage.

    Spring Loaded Footrest Extension
    A common complaint is a lack of pressure on the bottoms of the feet, or the length of the footrest is not accurate. With the spring loaded leg massager, there is a continuous pressure applied to the bottoms of the feet with the springs wanting to retract. This also avoids improper calibration in length. It will extend out to comfortably fit a user up to 6’3” depending if they are bottom or top long. The minimum height would be 5’, but if the leg rest is raised it may accommodate someone slightly shorter.

    Ergonomic Arm Massager
    The arm massager positions the arms so that the palms of the user are in towards the body. Inside the arm massager is a protective cover to reduce dirt build-up of the spandex material.

    Hip Compression Massage
    Along the side walls of the seat base are airbags that inflate and release, creating a squeezing action along the hips and outer thigh.

    Computer Body Scan
    Equipped with the latest technology, the massage rollers map out the back’s curvature with great accuracy, translating into a more effective massage hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized.
