📚 Research Sources

Formulas derived from ISO 9241-5 (ergonomic office standards), BIFMA G1-2013, and peer-reviewed studies on children's anthropometric furniture match (Castellucci et al., 2010; Panagiotopoulou et al., 2004).

Seat height = 92% of popliteal height (≈ 25.85% of stature). Desk height = seat + sitting elbow height above seat (≈ 14.95% of stature).
