4D Human-Like Massage System: Advanced 4D rollers combined with soothing airbags recreate a human massage sensation, offering 12 core motion settings, 5 techniques, 22 total massage modes, 15 preset programs and 32 targeted airbag points that cover the whole body. Three adjustable air pressure levels compress shoulders, arms, feet and hips to ease aches. Graphene lower-back heating delivers therapeutic warmth for both occasional and chronic discomfort. SL-Track Design: Extended SL rail runs from the neck down to the thighs, increasing treatment coverage by about 50%. Smart shoulder-position detection automatically adjusts massage position and back width to follow your body curves for precise, comfortable therapy. Zero Gravity Recline: Space-capsule style zero-gravity offers three incline levels to place the knees above the chest, reducing spinal loading, lowering cardiac strain and promoting circulation for deeper relaxation. Foot Rollers & Yoga Stretch: Full-roller kneading stimulates reflex points on the soles while leg airbags provide compression to relieve soreness. The backrest performs a deep yoga-style stretch to decompress and relax muscles. Intelligent Controls & Entertainment: Hands-free AI voice control plus a TFT touchscreen enable simple operation—speak your request and the chair launches the matching program. Built-in Bluetooth speakers let you listen to music while you unwind. Warranty & Support: Includes a 3-year protection plan, expert technical support and 24/7 customer service.
