The Solo Flex 4D Massage Chair combines intelligent wellness technology with advanced comfort for a fully personalized massage experience.
Its AI Health Detection scans your body to recommend the most suitable program, while the adjustable 4D massage mechanism delivers deep, human-like precision.
With innovative Walking Technology, the chair gently guides your lower body through a natural walking motion to stretch and relax the back, hips, and legs for enhanced recovery and comfort.
INTELLIGENT HEALTH DETECTION
The AI-powered health detection system analyzes key indicators—including heart rate, HRV, microcirculation, and fatigue levels—to recommend a massage tailored to your body's real-time condition.

ROBO WALKING TECHNOLOGY
Unlike standard massage chairs that often overlook the lower body, the Osaki Solo Flex 4D delivers balanced care with its unique scissor-action mechanism that mimics natural walking. This smooth, rhythmic motion gently stretches the glutes, hamstrings, and knees, promoting improved flexibility and a more complete full-body wellness experience.
4D MASSAGE
MECHANISM
MECHANISM
4D massage mechanism is an advanced roller system that moves in multiple directions—up and down, side to side, in and out, and with adjustable speed—allowing the massage to feel more natural and human-like. It can vary the intensity and rhythm, providing deeper pressure, smoother transitions, and a more customized massage experience compared to standard 2D or 3D mechanisms.
BODY SCAN
TECHNOLOGY

Body Scan automatically detects the user's shoulder height before the massage begins, allowing the chair to adjust the rollers for a more precise, customized, and comfortable massage experience.
3-STAGE
ZERO GRAVITY RECLINING
Inspired by NASA innovations, the Osaki Solo Flex 4D features advanced Zero Gravity Reclining technology that allows you to recline in 3 near-weightless positions, distributing your body weight evenly to reduce spinal pressure.
