Your Daily Reset

If you spend long hours at a desk, deal with daily stress, or find yourself with poor posture, you know the feeling of tight shoulders, lower-back pressure, and heavy legs. The Osaki OP-4D Master is engineered for consistent, effective recovery right in your home.

This chair combines precise 4D massage, comprehensive body coverage, and a comfortable recline. It helps you unwind after work, recover from activity, and maintain a steady routine without needing appointments.

Targeted Relief

The 4D roller system adjusts its speed, depth, and rhythm to better engage different muscle groups. This means your sessions can feel more controlled and natural, whether you need a steady pace or deeper pressure.

The track follows the natural curve of your back and seat, maintaining contact through your spine and lower body throughout the massage cycle.

  • 4D rollers for adjustable depth and pacing
  • Track-guided coverage for consistent contact along the back
  • Body scan support for more accurate roller positioning

Full-Body Comfort

Air compression gently wraps key areas, helping to reduce that heavy, tired feeling and support circulation. Heat in the lower back helps muscles relax before and during your massage. Foot and calf work supports daily lower-body recovery, especially after long days on your feet.

  • Air compression massage for full-body support
  • Lumbar heat therapy for lower-back comfort
  • Foot and calf massage for daily leg relief

Ergonomic Design

Zero gravity positioning redistributes your body weight, reducing spinal pressure and allowing the rollers to work more evenly. The chair reclines smoothly, fitting practically into your living space.

  • Zero gravity recline for reduced pressure
  • Space-saving recline design for easier placement
  • Power recline adjustments for your preferred angles

Effortless Experience

Choose automatic programs for a complete session without constant adjustments. Or, switch to manual controls when you want to focus on a specific area or change intensity. Bluetooth speakers allow for simple audio playback during your sessions.

  • Automatic programs for consistent sessions
  • Manual controls for targeted adjustment
  • Bluetooth speakers for audio playback
