4. Operating Instructions
The HealthRelife A337 Massage Chair offers various features for a personalized massage experience.
4.1. Intelligent Human Scanning System
Upon activation, the chair uses an intelligent scanning system to detect your shoulder width and height, customizing the massage to your body's specific points. The massage system then glides along a long SL guide rail, ensuring proper alignment with your back's natural curvature.
4.2. Full Body Airbags Massage
The chair features 40 airbags strategically positioned from the shoulder to the foot. These airbags apply rhythmic pressure through air compression, helping to relieve muscle tension and improve blood circulation. The foot and calf massage specifically targets these areas with air compression and rotating finger pressure.

4.3. Zero Gravity & Stretching Mode
The chair offers two zero gravity recline positions. In this position, your heart and knees are aligned, which reduces heart pressure and enhances blood circulation. This mode promotes deep and relaxed breathing while relieving pressure on your joints and spine. Activate this mode using the control panel or remote.
