A list of available voice commands is typically located on the back of the LCD touch screen.

4.3 4D Massage Mechanism and SL-Track

The chair features an advanced 4D flexible deep fascia massage mechanism that mimics human hands. The massage rollers move along an extended SL-track, providing comprehensive coverage from the neck to the hips.

• 4D Massage: Adjusts massage width (1.2-8.5 inches), depth (up to 4.8 inches), and intensity (3 levels).
• SL-Track: The 54.6-inch (138.7 cm) SL-track ensures the massage rollers follow the natural curve of your spine, providing targeted relief for the neck, shoulders, back, hips, and thighs.

4.4 Automatic Body Scanning

Upon activation, the chair performs an automatic body scan to detect your body shape and size. This allows the massage rollers to adjust their position and intensity to provide a personalized and accurate massage experience.

4.5 Massage Programs and Techniques

The chair offers 5 auto modes and 5 massage techniques, including Shiatsu, Kneading, Tapping, Knocking, and a combination of Tapping & Kneading. You can also adjust the massage intensity to 3 levels.

4.6 Zero Gravity Function

The zero-gravity feature reclines the chair to an angle where your knees are elevated above your chest. This position reduces spinal compression, decreases pressure on the heart, and improves blood circulation, enhancing the massage experience.

• Multistage Zero-Gravity: The chair offers multiple inclination angles for the zero-gravity position.

The chair incorporates 32 airbags strategically placed throughout the body to provide compression massage. The waist area features heating elements to further relax muscles and improve comfort.

4.8 Foot Rollers and Stretching

Full-roller kneading on the feet stimulates acupoints, while enveloping airbag pressure on the legs helps relieve soreness. The chair also offers a stretching function, inclining the backrest to stretch your upper body and release fatigue.
