Body Movement

Dynamic lumbar support that's always got your back

The BM (Body Movement) Tracking System ensures that the lumbar support automatically conforms to your spine, providing comfort and support for your back during different postures, without the need for manual adjustment.

Flexible backrest, continual back support

When you move your upper body around or reach down to the side to pick up a pen you dropped, the streamlined backrest of the Doro-C300 with a triangular frame flexes and matches your back, providing continuous support.

Rest your neck in high precision
