Design & Build Quality
From appearance to construction, the Tecno feels like a premium product. Its upholstery, stitching, and aesthetics are clean and modern. The light brown (or taupe) finish is neutral, allowing it to integrate well into many home decor styles.
The SL-track design ensures the rollers maintain close contact with the back’s natural curvature — reaching from the neck and shoulders down into the lower back and glutes. The frame feels sturdy, and despite its size, the “space-saving” recline mechanism means it doesn’t need excessive clearance behind it when reclining — a big plus in tighter rooms.
The automatic footrest extension is a thoughtful touch, adapting to users of different heights without requiring manual adjustment.
Massage Performance & User Experience
1. 3D Roller System & Customization
Where many chairs use fixed-depth rollers, the Tecno’s 3D capability allows the rollers to move deeper or pull back, giving you control over how intense the massage is. Coupled with speed and strength settings, this allows tailoring from gentle relaxation to deeper, therapeutic pressure.
2. Body Scanning & Intelligent Adjustment
On startup, the chair performs a body scan to map your height and shoulder position, helping align the rollers and airbags for optimized coverage. This automation reduces manual setup and ensures better alignment especially after recline adjustments.
3. Compression & Air Massage
With 38 air cells distributed across shoulders, arms, waist, hips, calves, and feet, the Tecno provides a well-rounded compression massage that complements roller movements by gently squeezing and releasing muscles to improve circulation. This helps those hard-to-reach regions where rollers can’t act.
4. Zero Gravity Recline & Stretching Effects
The zero gravity mode lifts your legs above heart level, distributing your body weight more evenly and reducing pressure on the spine. In this position, the massage feels deeper without needing more force. The combination of zero gravity and SL-track gives you a more immersive and effective session.
5. Heating & Foot Therapy
The lumbar and calf heating options add soothing warmth—especially helpful when muscles feel stiff or cold. The dual foot rollers knead the soles, toes, and heels, combined with calf kneading and air wraps, for full lower-leg therapy.
6. Programs & Control Options
With 9 auto programs and 5 massage styles (kneading, tapping, shiatsu, rolling, etc.), the Tecno offers enough variation to suit many needs. Adjustments in intensity, speed, and focus areas let you fine-tune each session.
Bluetooth speakers let you play relaxing music, ambient audio, or guided meditations for an immersive massage environment.
