The Pro-Wellness PW570 uses a 3D massage mechanism with contact sensors that scan the user's back contour before each session, guided by a 120 cm L-Shape rail that reaches from the neck down through the buttocks — designed to ease tension linked to sciatic discomfort. 23 combinations of back massage techniques are available, each adjustable across 3 levels of kneading intensity, tapping speed and width.12 automatic programs are included (11 themed routines plus a 5-minute Quick massage), spanning Relaxation, Stretching, Spinal Therapy, Swedish, Thai, Japanese, Chinese and Balinese-style sessions, and users can build and save 3 custom programs of their own. 38 airbags handle compression massage across the shoulders, forearms, hands, calves and feet, complemented by a 3D shiatsu foot roller and lymphatic-style calf massage. Two pre-set Zero Gravity positions reduce spinal load, and lumbar heating can be toggled independently of the back massage.Controls run through a 7-inch touchscreen with Polish/English menus, and the chair includes built-in Bluetooth speakers. Seated footprint 79×127×162 cm, reclined 79×92×190 cm. Peak power draw 130W at 230V. Weight approximately 106 kg.
