Top Features of the JPMedics KaZe

AI-Powered Chair Doctor Customization

The Chair Doctor feature uses advanced AI and biometric sensors to create a massage uniquely tailored to your body’s current condition.

By measuring heart rate with PPG technology and analyzing stress through GSA Control sensors, it evaluates your physical and emotional state. It also monitors your SPA Blood Oxygen Levels to understand your tension levels better.

All of this data allows the chair to make real-time adjustments, delivering a massage personalized to how you feel at that exact moment. This intelligent system ensures your massage experience is not only relaxing but also meaningfully aligned with your body’s specific needs.

Vario Motion 4D with Extended L-Track

The KaZe massage chair includes a 4D L-Track design, extending approximately 1.35 meters from the head and neck down to the glutes.

This long track allows the massage rollers to follow your spine’s natural curve and address 36 acupressure points across your back and lower body.

Powered by JPMedics’ proprietary Vario Motion 4D engine, the chair uses four massage rollers to deliver a consistent and precise experience. This system provides smoother, more responsive strokes that mimic human hands.

The combination of track length and advanced 4D movement ensures effective relief across a broad portion of the body.

Convenient Voice Command Capability

The JPMedics KaZe massage chair features voice control compatibility with Alexa and Google Assistant, making it easy to operate without lifting a finger.

Use simple voice commands to start, stop, or adjust your massage, all without needing the touchscreen remote or quick control dial. Perfect for uninterrupted relaxation, this hands-free option adds modern convenience to your session.

Just download the appropriate app from the Apple Store or Google Play, pair it with your smart speaker, and you're ready to go.

Voice control gives you seamless access to key functions, enhancing your overall experience with intuitive, effortless operation.

Three-Zone Heat Therapy Coverage

The KaZe massage chair features targeted heat therapy zones in the lumbar, seat, and calf regions, helping relax muscles and promote deeper tension relief.

These three heated areas work together to improve blood flow and soothe tight muscles during your massage. The lumbar heat focuses on the lower back, while the seat and calf zones ensure a more full-body warming experience.

This combination enhances comfort and maximizes relaxation, especially when paired with the chair’s massage functions. Whether used before or during your massage, heat therapy supports stress relief and contributes to a more therapeutic session overall.

Built-In Wireless Charging Convenience

The JPMedics KaZe massage chair includes a built-in wireless charger, allowing you to power your smartphone while enjoying your massage. This feature adds everyday convenience by eliminating the need for separate cables or outlets during your session.

Simply place a compatible device on the designated charging pad, and it begins charging automatically.

It’s a small but thoughtful touch that enhances the chair’s overall usability,  especially if you like to keep your phone nearby for music, notifications, or relaxation apps.

This seamless charging solution fits naturally into your routine, letting you unwind without interruptions.
