The Osaki OP-4D Ultima combines a 4D massage mechanism with computerized body scanning and intelligent voice control on an SL-Track, wrapped in a wall-hugger design that reclines fully in tight spaces. Twelve auto programs and six massage styles pair with an extensive 48-cell full-body air compression system.

Lumbar and calf heating soothe from the core outward, while a triple-action foot massager and automatic extendable footrest give the lower body serious attention. A touchscreen controller, shortcut panel, and surround-sound Bluetooth speakers make every zero gravity session effortless.
