    Osaki OS-4000CS massage chair

    The Osaki OS-4000 CS is part of the bestselling OS-4000 Series, offering an array of innovative features like space saving technology, L-Track Massage, Adjustable Shoulders and Zero Gravity. Each chair in the OS-4000 series has something unique to offer.

    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 are curved to the contour of your back and glutes area.

    Space Saving Recline Technology

    Typical massage chairs take up considerably more space (up to three feet in some cases) when the chair is in a reclined position, making them impossible to put close to walls. Osaki's innovative design team has engineered a space saving technology that slides the chair forward as the chair reclines. Fully reclined this massage chair can be positioned within 6 inches of a wall for maximum space saving.

    Lumbar Heating Pad

    There are individual heating pads on each side of the lower lumbar area. Heat therapy, which is known to increase blood circulation and loosen tense muscles, is a great compliment to the roller and airbag massage. Note: the heating pad is not intended to be used more than 30 minutes per 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 helps maximizes the massage intensity.

    6 Massage Techniques

    The Osaki OS-4000 CS has 6 unique massage styles: Kneading, Tapping, Rolling, Shiatsu, Kneading & Tapping and Kneading & Shiatsu.

    24 Airbag Massage

    Osaki strives to make its chairs efficient and extremely reliable. Many other brands will market their chairs to have 70+ airbags for a full body massage. Unfortunately, the more airbags and more valves a chair has, the more strain is put on the air pump, creating a greater chance of something failing. Osaki engineers its chairs to reduce the airbag count while at the same time increasing the surface area, using more pliable and durable materials. All 24 airbags are strategically placed to optimize the squeezing effect on 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. With most other manufacturers' chairs, the outer massage airbags are stationary and depending on the height and width of the user, the shoulder massagers can be ineffective because they are not positioned correctly for the individual that is in the chair. Because you can adjust the Osaki™ OS-4000CS Massage Chair to 3 different widths, each individual can improve the strength and fit of the outer shoulder massage area.

    Spring Loaded Footrest Extension

    A common complaint heard about other manufacturers' massage chairs is a lack of pressure on the bottoms of the feet or that the length of the footrest is not correct. With this chair's spring loaded leg massager, there is a continuous pressure applied to the bottoms of your feet. Additionally, length is not an issue because the footrest can extend or retract to comfortably fit any user from 5' to 6’ 3” tall.

    Ergonomic Arm Massager

    The position of the arm massager places the palms of the user in towards the body. Inside the arm massager are protective covers to reduce dirt build-up from 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.
