Osaki OP-4D Master Massage Chair

Overview

Long hours sitting, daily stress, and poor posture often show up as tight shoulders, lower-back pressure, and heavy legs at the end of the day. Short breaks help, but the tension returns. The Osaki OP-4D Master is designed for consistent, repeatable recovery at home.

It combines controlled 4D massage, full-body coverage, and comfort-focused recline so you can reset after work, recover after activity, and keep a steady routine without scheduling appointments.

Massage Technology

The 4D roller system adjusts speed, depth, and rhythm to better match different muscle groups. Sessions can feel more controlled and natural when you need a steady pace or deeper pressure.

Track coverage follows the back and seat line to maintain contact through the spine and lower body during 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 when available

Comfort & Body Coverage

Air compression wraps key areas to reduce that heavy, tired feeling and support circulation. Heat in the lower back helps muscles relax before and during massage. Foot and calf work supports daily lower-body recovery.

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

Recline & Ergonomics

Zero gravity positioning redistributes body weight to reduce spinal pressure and help the rollers work more evenly. The chair is designed to recline smoothly while staying practical in real rooms.

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

User Experience

Use automatic programs when you want a full session without constant adjustment. Switch to manual controls when you want to focus on one area or change intensity. Bluetooth speakers support simple audio playback during sessions.

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