4-layer matrix
Inspiré des selles des cyclistes d'endurance, notre siège à 4 couches combine une maille respirante, de la mousse à mémoire de forme, du TPE et une matrice à ressorts avec 62 nœuds et 186 entretoises, utilisant des principes biomécaniques pour répartir la pression uniformément sur la zone des os de votre siège. Fini les douleurs aux fesses !

Adaptive backrest
The design features flexible ribs that remove hard edges, enabling smooth posture adjustments and keeping your spine aligned, so you stay active and healthy.
Invisible lumbar support
X-shaped lumbar support helps you maintain good posture by giving just the right amount of support to your lower back, while keeping your shoulders free to move naturally.
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.
Air mesh technology
Air Mesh is 3-5x more breathable than regular mesh. You'll stay cool and dry, even on those crazy long focus days - that's one less thing to worry about!
