2M2Kids Brill Study Chair: 4-Step Adjustment Guide

Proper adjustment is key to unlocking the chair's ergonomic benefits. Just four steps to protect your child's posture.

1. Seat Height: Feet Flat

Adjust the seat height until your child's feet rest flat on the floor, with thighs and calves forming a 90° angle. This is the foundation for a stable posture.

2. Seat Depth: Knee Comfort

Adjust the seat depth so about a fist's width of space remains between the seat edge and the back of the knees, preventing pressure and ensuring good circulation.

3. Backrest Height: Support Back

Adjust the backrest height so its top point rests just below the shoulder blades, providing upper back support while ensuring the lumbar pad correctly contacts the lower back.

4. Lumbar Depth: Engage Lower Back

Fine-tune the lumbar depth until it feels supportive and makes full contact with the lower back, helping maintain the spine's natural curve and prevent slouching.

Core Principle: Follow the "Height → Depth → Backrest → Lumbar" sequence for synergistic adjustment. Re-adjust periodically as your child grows for continuous protection.
