    Computer Body Scan

    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.

    Picture

    Unique Foot Roller

    Located on the bottom of the feet are 2 rows of spinning reflexology massagers which provide a soothing kneading style application. As the rollers spin it will stimulate acupuncture points and as the air bags inflate it will generate a much deeper massage along the bottoms of your feet.

    Picture


    Zero Gravity Massage

    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 feature improves spinal decompression and decreases muscle tension of the spine. There are 2 stages of zero gravity, the 2nd being more reclined. When reclined fully, to where your legs are higher than your heart level, the therapeutic effects are incredibly effective and may be felt immediately.

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

    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.

    Picture

    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.

    Picture

    Calf & Foot Massage

    There are multiple air bags along the sides and back of the legs and feet which inflate to apply a compression massage. Located along the bottom foot massager are spinning rollers that apply a concentrated pin-point kneading massage.

    Picture

    Lower Back Heat Therapy

    Placed in the lower back region of the chair are 2 heating pads that enhance the massage experience.

     Picture

    Shoulder, Lumbar & Hip Squeeze

    In the upper to mid portion of the chair, the air bags are programed to inflate at independent times, which causes the body to twist, creating an enjoyable deep stretch. Stretching is applied to the shoulders, lower back, hips, and thighs.

    Full Size Easy-to-Use Remote 

    The OS-4000T remote presents one of the largest viewing screens to easily visualize what functions the chair has activated. There is also a flip down cover to access the manual functions of the chair. The remote allows you to select the massage type, intensity, speed and location. You can also independently select  the area of airbag massage. The manual mode massage includes kneadingtappingshiatsurollingcombination and Swedish.

    Picture

    • Air Intensity Adjustment - The air intensity of the air bags can be controlled up to 5 levels, from mild to strong.
    • 3 Levels of Intensity for the massage - The roller heads that apply the massage to the back, can be extended outwards causing the rollers to press more firmly along the back. This will result in a more vigorous massage.
    • Massage Speed Control - The speed in which the massage heads move can be controlled up to 3 different speeds, ranging from slow to fast.

    Picture

    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 chair will fully extend out and then retract. Once the foot massager has reached the desired length, firmly press your totes down to indicate the chair to stop.

    Picture

    Seat Vibration

    Located in the seat base is a vibration plate that provides a vibration massage to the back of the thighs.

    Bought this chair my husband and he loves it. Helps his shoulder and neck pain. Loved being able to pay for this in 12 payments. So worth it when spending more time at home this year!
