Osaki OP-4D Master Massage Chair, SL-Track, Zero Gravity, AI Muscle Tension Detection, Alexa Voice Control

The Osaki OP-4D Master Massage Chair is a full-featured SL-Track chair engineered for daily therapeutic use. It combines AI muscle tension detection, a 4D massage mechanism, 46 air cells, and Alexa voice control in one system. Over-the-Shoulder Airbag Massage The standout feature is the over-the-shoulder airbag massage system. It uses 10 synchronized airbags that rotate and move the way a therapist's hands do. Extra massage nodes on each side add a hand-massage feel to the shoulders. AI Muscle Tension Detection The Health Pro AI scan detects areas of concentrated muscle tension across your torso. It builds a customized session based on your body's condition that day. This adjusts technique, pressure, and duration for a personalized massage every time. 4D Massage Mechanism and SL-Track The 4D massage mechanism offers multiple levels of adjustment across intensity, strength, and speed. It can spot-treat or partially massage specific back areas. The laser-crafted steel SL-Track extends from the neck and shoulders to the hamstrings. Programs and Reclining 16 auto programs and 6 manual massage styles cover a wide range of techniques. One-stage zero gravity reclining, pioneered by NASA, reduces pressure on the spine. Space-saving design needs just 3 inches of wall clearance for a full recline. Heat Therapy and Lower Body Care Lumbar and feet heating coils warm and soothe soreness in the lower back and feet. Calf massage combines kneading rollers with airbag compression for tired leg muscles. Specialized foot rollers activate acupuncture points from heel to toe. Fit and Extras The automatic extendable footrest elongates up to 8 inches for users of different heights. An attachable magnetic pillow adds extra shoulder support during your session. Smart Controls and Connectivity Control the chair through Alexa voice commands, the Osaki Premium Master app, or the swivel-mounted touchscreen controller. A side control panel, Bluetooth surround sound speakers, and LED mood lighting round out the design. A USB charging port, phone charging surface, and negative oxygen ion therapy complete the experience.
