Osaki OP-4D Master

The Osaki OP-4D Master is a single-mechanism 4D SL-track chair built around shoulder work. Over-the-shoulder airbags (Osaki lists 10) rotate and move with extra nodes in the shoulder pads, and an automatic scan sets shoulder height and width before the rollers start.

Muscle-tension detection (Health Pro) shapes a program from what it finds in the torso. You can run the chair from the touchscreen, the Osaki Premium Master app, or Alexa voice commands as published. Negative oxygen ions, lumbar and foot heat (about 75-83 F), and 46 air cells round out the session.

One-stage zero gravity with about 3" of wall clearance keeps it in a normal room. Easy Home Wellness is an authorized Osaki dealer. Call before freight so we can confirm the 31.5" doorway and the 8" footrest extension range.
