Adaptive support from head to hips. Every adjustment, every material, every detail is designed around your body.
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.

Six adjustment zones work together to fine-tune every contact point — from your head and shoulders to your lumbar and legs.
A four-way stretch weave disperses pressure in every direction, creating balanced support that reduces pressure points and keeps you comfortable through long hours of sitting.
Inspired by the feeling of human touch, the 4D biomimetic massage system combines with graphene heat technology to bring targeted warmth and relaxation to your lower back.
“Fingertip” Feel - Raised massage heads recreate the focused pressure of fingertips, delivering a deeper and more targeted massage sensation.
“Finger Pad” Feel - Rounded massage heads mimic the softness of finger pads, creating a gentle kneading experience for everyday relaxation.
Graphene far-infrared radiation penetrates deep into lumbar muscle tissue — promotes blood circulation and relieves chronic fatigue.
A graphene heating layer spreads warmth evenly across the support area, creating lasting comfort whenever you need it.
Seamlessly integrated into your workday. Enjoy a moment of relaxation without leaving your desk.
