Oversize 4D Full-Body Massage Chair - Zero Gravity Recliner with 135cm SL-Track, O2 Ionizer, Motorized Calf Extension, Kneading, Yoga Stretch, Back Heating, 20 Modes (Ivory)

4D Full-Body Therapy & Long SL-Track: Equipped with 4D roller motion and a 135 cm SL-track, this chair reaches from neck to thighs. Forty airbags run from shoulders to feet while back heating and kneading functions, plus foot rollers, provide comprehensive relief for every zone. Customizable, Personalized Massage: The chair performs an automatic body scan to locate shoulder height and tailor treatment. Users can individually adjust roller speed, width, strength and airbag pressure. Backrest and leg angles are motorized for personalized positioning. O2 Ionizer & 3D Surround Sound: An O2 ionizer built into the headrest releases negative oxygen ions to help purify air and support metabolism. Built-in 3D surround Bluetooth speakers let you play music during sessions for enhanced relaxation. Versatile Techniques & Stretch Modes: Includes a variety of functional routines—Thai-style stretching that lengthens and decompresses back, waist and legs, plus a 3-level zero-gravity position that reduces body load and helps muscles relax. The system supports multiple preset routines and massage techniques to meet diverse needs. Human-Centered Design & Controls: Updated with customer feedback, the chair allows independent control of upper and lower body airbags and offers adjustable voice prompts and buzzer volume. We back our product with friendly customer service and a 3-year protection commitment.
