First-of-its-kind Thorough Shoulder Massage The first-ever over-the-shoulder massage using airbag compression that rotates and moves like real hands, with 10 individual airbags synchronized for a soothing massage. AI Scan Automatic Shoulder Adjustment An automatic body scan detects your shoulder height and width, then repositions the massage rollers for a more effective, personalized massage. Health Pro Muscle Tension Detection The Health Pro program detects tension in your torso and tailors a massage program to your specific needs, since every body is different. Engineered for Total-Body Relief Shoulder Massage Nodes An extra massage node on each side of the shoulder pad emulates the feel of a hand massage, layering onto the airbag compression for a more complete shoulder session. 10 airbags · Rotating motion · Hand-like compression Touchscreen Controller The swivel-mount touchscreen controller allows for easy navigation and adjustment, and can be conveniently positioned at different angles for effortless reach. Swivel mount · Intuitive navigation · Full control App & Smart Voice Control Download the Osaki Premium 4D+ Master app (iPhone or Android) to control the chair from your phone, or use Smart Voice Control — just say "Alexa" or "Hi, Osaki" followed by a command. iOS & Android app · Alexa compatible · Hands-free control 4D+ SL-Track System Made of laser-crafted steel, the SL-Track lets the 4D+ rollers freely reach your entire body — extending all the way from your neck and shoulders to your hamstrings, with 4 and 5 levels of intensity, strength and speed. Neck to hamstrings · Laser-crafted steel · Spot & full-back treatment Zero Gravity Reclining & Space Saving Encounter relaxation in a state of weightlessness with NASA-inspired zero gravity reclining. Space Saving Technology lets the chair sit just 3 inches from the wall and still achieve a full recline.

Up to 8" extension · Spring-loaded · Fits any height Calf & Foot Rollers A sequence of kneading rollers moves vertically through the calves while airbag compression handles the rest, and specialized foot rollers activate acupuncture points along scientifically designed reflexology ridges — three rollers per foot, heel to toe.
