VOLUME I: The Biomechanical Debt

In 2026, the "Sedentary Debt" has become a primary health concern in European tech hubs. Clinical research from the Journal of Orthopedic Research shows that unsupported sitting increases intradiscal pressure by 90% compared to standing. For the "Big & Tall" demographic (100kg+), this pressure is compounded, leading to premature disc degeneration.

The ReliefBack Pro3 wasn't designed as a chair; it was engineered as a postural exoskeleton. Its core mission: to neutralize the vertical load of gravity and distribute it across a dynamic structural mesh.

VOLUME II: The 8D Dynamic Lumbar Revolution

Most chairs, like the SIHOO Doro C300, utilize a spring-loaded lumbar that moves in 2 or 3 directions. The Pro3 introduces 8D Dynamic Tracking. But what does "8D" actually mean for your spine?

• [+] Synchronized Depth: The lumbar support doesn't just push forward; it adjusts its depth based on the curvature of your L1-L5 vertebrae.
• [+] Lateral Pivot (Torsion): As you reach for a coffee or twist toward a second monitor, the lumbar wings pivot independently, ensuring 100% contact area at all times.
• [+] Height Micro-Adjustment: 15 levels of vertical precision to target the exact "sweet spot" of your lower back arch.

VOLUME III: Engineering for the 200kg Benchmark

Why did MELOKEA push the limit to 200kg (440 lbs) when the average person weighs much less? Structural Fatigue.

A chair rated for 120kg (like Ergotopia NextBack) operates near its elastic limit when a 100kg user sits down. This leads to frame "creaking" and mesh sagging within 18 months. By engineering the Pro3 for 200kg, we ensure that for an average user, the chair is operating at only 40% of its capacity, effectively tripling its structural lifespan.
