The Osaki OP-4D Master pairs deep 4D massage with intelligent muscle tension detection: the chair locates stiff, knotted areas along the SL-Track and concentrates its work there at intensity levels 6 to 7. Sixteen auto programs and six massage styles pair with 46 air cells of full-body compression and soothing lumbar heat therapy.

Zero gravity recline, space-saving technology, an automatic footrest, and surround-sound Bluetooth speakers make daily use effortless. Includes an official 5-year warranty, with a free cleaning kit during the current promotional event.
