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.

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.

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.

Air Arm Massagers

Along with mechanical advancement, the material has also incorporated some upgrades, such as the arm massaging area. Using a durable spandex, the bottom portion of the arm massager has been lined with small rubber bumps to invigorate the senses as the air bags compress the tops and bottom of the forearm and hands.

Lower Back Heat Therapy

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

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.

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.

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.
