Built with a sturdy frame and modern aesthetic (in “Deep Black” finish), the MT339 is engineered to adapt to different users and deliver precise, soothing pressure across the body. Whether for daily recovery, stress relief, or mobility support, it’s more than a chair — it’s a therapeutic tool.

Design & Build Quality

• The Deep Black upholstery is elegant and practical, offering a polished look that fits well in living rooms, home offices, or wellness spaces. The materials feel durable yet comfortable.
• The SL-track (versus simple linear tracks) lets the rollers follow the natural curvature of your spine — from neck to glutes — ensuring contact across the full back area.
• The chair includes an auto-extendable footrest which adjusts automatically to your leg length, meaning whether you’re tall or short, your knees and calves are supported properly.
• The frame design supports a zero-wall footprint — meaning it doesn’t need large clearance behind it to recline fully — making it room-friendly.
• Control panels and armrests are ergonomically placed. The build feels solid, and transitions (recline, stretch, lift) are smooth and stable.

Massage Technology & Performance

4D Roller System

Unlike traditional 2D or 3D chairs, the MT339’s 4D rollers can adjust in speed, depth, and rhythm. This dynamic motion lets you feel more realistic massage techniques — from kneading and tapping to rolling and shiatsu pressure. You can fine-tune how forceful or soft the rollers act, depending on your comfort and muscle tension.

SL-Track Coverage

Because of the SL-track design, the rollers maintain closer contact with the spine’s S-curve. This means better reach in the lumbar region and across the lower back — areas particularly prone to tension — compared to chairs using straight tracks.

Airbag Compression & Foot Rollers

Airbags in the shoulders, arms, waist, hips, calves, and feet work in sync with the rollers, compressing and releasing the muscles in a wave-like pattern, improving circulation and complementing the roller pressure. The integrated foot rollers provide targeted kneading across soles and heels, which helps relieve foot fatigue and stimulate reflex zones.

Zero Gravity & Stretch Mode

With a push of a button, the MT339 enters zero-gravity recline, positioning your body so that your weight is evenly distributed — taking pressure off joints and spine, and enhancing the effectiveness of the massage. The deep yoga stretch mode gently pulls your body into stretches, decompressing vertebrae, opening the hips, and enhancing flexibility.
This combination is especially beneficial for users who spend hours sitting or have stiff, tight muscles.

Heating Function

Heaters built into the lumbar and calf zones provide soothing warmth that loosens muscles, eases stiffness, and increases circulation. When paired with the massage, it enhances comfort and effectiveness, particularly for lower back discomfort or cold-sensitive muscle areas.

Smart & Custom Controls

• 15 Auto Modes: Ranging from Relax, Deep Tissue, Neck & Shoulder, Full Body, Sleep, Stretch, Recovery — there’s a preset for nearly every mood or need.
• AI Voice Control: Command the chair hands-free — adjust modes, intensities, recline positions, or heat settings without reaching for a remote.
• Mobile App / Remote Interface: Fine-control over speed, depth, roller width, air pressure, zones to focus (neck, back, legs), and program creation.
• Memory Presets: Save your preferred settings so you can jump into your customized massage without reconfiguring every time.

Real-World Use & Comfort

The MT339 delivers a balanced experience: when you want a firm deep-tissue massage, the rollers press confidently; when you want gentle relaxation, it scales back pressure. The transitions are smooth. The airbag compression is noticeable but never jarring.

During Stretch Mode, the pull is gradual and controlled — not aggressive — making it reachable even for users with limited flexibility. The foot massage tends to receive praise; combining roller kneading and compression wraps brings real relief after long standing or walking days.

Even with all features active (rollers, airbags, heat), the chair operates at a reasonable noise level, allowing you to read or listen to music while you enjoy the session.

For regular users, fatigue, neck stiffness, lower back soreness, and tension areas often show tangible improvement after a few weeks of consistent use. Many describe it as a “home spa massage lightened daily.”
