Osaki OS-4000 Zero Gravity Executive Full Body Massage

    Osaki OS-4000 Massage ChairComputer 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.

    Osaki OS-4000 Massage Chair2 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.

    The OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety spine shapes. The Spine curvature is unique form 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.

    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 but yet soft and pliable to provide comfort and consistency.Osaki OS-4000 Massage Chair
