Adaptive support from head to hips. Every adjustment, every material, every detail is designed around your body.
Fine-tuned support from head to hips.
Breathable comfort with lasting elasticity and durability.
Premium materials and reinforced construction built to perform for years.
Unlike fixed backrests, the 5° flexible linked backrest moves with your body. A 12-rail, 8-axis, and 3-spring system keeps support continuous through every posture change.
Three independent zones work in concert to deliver continuous, adaptive lumbar support — no matter how you sit, lean, or move.
Traditional split-back chairs can create a gap where your lower back loses support, leading to pressure buildup and fatigue over long sitting sessions. E3 Gen5’s adaptive tracking system keeps support aligned with your movement.
