Highlights at a Glance
3D Wide-Fit Headrest
28% More Surface. More Neck Support.

Soft Support That Stays With You.
Three-way adjustment and built-in cushioning help reduce pressure and keep support close through every shift.
4-Zone Synchronized Tracking
Coordinated Support Across 4 Key Zones
From head and neck to back, waist, and arms, four support zones move together with your body.
Moves With You. Stays Aligned.
Support follows your body as you lean, shift, and recline — helping comfort stay where it should.
SyncroFlex™ Glide System
Fits Different Body Types More Naturally
SyncroFlex helps the backrest adjust as you sit, creating a closer fit for different body types. It feels more natural from the very first lean.
Keeps Support in Place as You Move
As you lean back or shift, the backrest moves with you. This helps keep support close to your back and waist, so comfort feels more consistent.
Domino™ Sacral-Lumbar Support
Support Where It’s Usually Missing
Not just for the lumbar. It helps support extend down toward the sacrum, filling the space where comfort is often lost.
More Contact. Less Pressure.
A broader, more flexible surface helps support feel smoother, more even, and more natural in every position.
8D Bio-Adaptive Armrests
25% More Surface. More Support.
A larger armrest surface supports more of your forearm, helping reduce pressure on the shoulders and elbows.
Ready for Every Position.

For every work rhythm
Let your back relax while you work. Stay comfortable, stay focused. Lean back and stay in your creative flow. Lean back and enjoy every moment.
