4D Stretch & Recovery Chair

Osaki 4D Yoga Flex Massage Chair

Most chairs leave the lower body to the air bags. The Yoga Flex adds an independent leg massager with a scissor-action mechanism that mimics walking, pulling and extending the legs to stretch the lower back, glutes, hamstrings, and knees. For runners and lifters, that's the part of recovery a standard chair skips.

On top of the walking system sits a true 4D mechanism that moves up, down, side to side, in and out, and changes speed in real time. An AI health detector reads your body's condition and tunes the session, so the stretch and the massage match what you're carrying that day.

The Technology

Four systems behind the stretch

The Yoga Flex pairs a 4D roller with a flexible track and automatic body mapping, so the pressure and the recline track your body instead of a default setting.

🤖
4D Massage Mechanism
The rollers move up, down, side to side, and in and out, and adjust speed in real time. That extra axis of movement is what lets the chair read closer to a therapist's hands than a fixed 3D stroke.
Multi-axis + variable speed
🛤️
SL-Track System
A laser-crafted steel SL-track guides the rollers in one continuous path from the neck and shoulders down to the hamstrings, covering the full spine and lower body in a single pass.
Neck to hamstrings
📡
Body Scan Technology
Every time the chair powers on it scans your full body to map your shape and size, then adjusts the rollers automatically so the massage fits your back rather than an average one.
Scans on every start
🪶
3-Stage Zero Gravity
Three zero-gravity recline stages tilt you progressively further back, spreading body weight evenly and relieving pressure points so the rollers work into an unloaded spine.

A closer look at how it works

Air walking leg massager
Air Walking Technology

A scissor-action leg massager that mimics walking

An independent leg massager pulls and extends the legs through a scissor-action walking motion, stretching the lower back, glutes, hamstrings, and knees. A separate Revolution calf system adds three modes, Walk, Wave, and Stretch, and can layer onto any of the auto programs.

  • Stretches lower back, glutes, hamstrings and knees
  • Revolution calf system: Walk, Wave, Stretch
  • Layers onto any automatic program
Lower-Body Stretch Calf Recovery
AI health detection
Intelligent Health Detection

An AI that reads your body before it works on it

An onboard health-monitoring system tracks your health index, and the AI uses that data to deliver a massage tailored to your body's condition in real time. The session adapts to you instead of running the same routine regardless of how you arrived.

  • Tracks your real-time health index
  • AI-personalized massage delivery
  • Adjusts the program to your condition
AI-Tuned Ai Series
34-cell air compression and heating
Air & Heat

34 air cells plus heat where muscle holds tension

Thirty-four air cells positioned through the chair deliver targeted compression to move blood and ease tension across the body. Heating in the lumbar and calves, at roughly 75–83°F, warms the areas that tighten most after training so the compression goes in easier.

  • 34 strategically placed air cells
  • Heat in the lumbar and calves
  • Approximately 75–83°F at the pads
Compression Lumbar + Calf Heat
Vibrating seat massage
Vibrating Seat

Seat vibration for the hips and thighs

A vibrating seat works the hips and thighs, areas rollers and air bags reach poorly. The vibration stimulates circulation through the seat, rounding out a massage that otherwise concentrates on the back and legs.

  • Targets the hips and thighs
  • Stimulates circulation through the seat
  • Adds coverage rollers miss
