The Pro-Wellness PW815 is a flagship massage chair featuring dual 5D+4D massage mechanisms that operate independently on the upper and lower back along a roughly 157 cm Open Flex rail, allowing a deeper recline than a standard Zero Gravity position for Thai-style full-body stretching. A wireless AI Health Check sensor reads fatigue, blood oxygen, HRV and microcirculation to help select a suitable program, and automatic body scanning maps spine length and tension points.The chair runs 31 automatic programs and 19 manual massage techniques (including kneading, shiatsu, scraping, pinching and pressing) across basic, targeted, relaxation, ritual, health and specialized categories. 57 air chambers deliver full-body compression massage, and three separate heating zones cover the lumbar, hip and knee areas. The footrest combines calf-scraping side rollers, leg compression, knee heat therapy and dual sole rollers.Additional features include a 12.3-inch touchscreen with quick-access panel, wireless phone charging and USB-C, a four-speaker audio system with YouTube and iOS screen mirroring, Wi-Fi, English voice control, LED ambient lighting, and aromatherapy with air ionization across 3 scent sets. Seated footprint 80×123×162 cm, reclined 80×94×194 cm. Peak power draw 260W at 230V. Weight approximately 141 kg.
