Fully Adjustable
Adaptive Backrest.
Innovative ribs keep the backrest flexible and tensioned, eliminating hard edges. Enjoy seamless posture changes with a backrest that flexes and twists with you.
Back Fit
Invisible Lumbar Protection.
Wider and directly tensioned by an X shape at the lumbar region maintain good posture, while thinner and more elastic near the shoulders give unrestricted movement.
Back Frame Design
Posture Alignment.
Inspired by the human spine with flexible ribs. The design aligns the backrest with your spine’s curve, providing constant support whether leaning forward or reclining.
Ventilation
Air Mesh.
Stitched directly onto the webbing, air mesh enhances edge flexibility and breathability, keeping you cool and comfortable. No more sweaty back!
