3D Intelligent Suspension Technology
Our work with Yves Béhar achieved a breakthrough in seating technology. Support is molded directly into the 3D Intelligent back material. The suspension material is stretched from the Y-Tower at the back of the chair just as cables are stretched from the towers of a suspension bridge. The tension is greater in the transition areas, from the thoracic to the lumbar areas and between the lumbar area and sacrum. "Hinge points" allow these areas to flex and support the healthy, forward rotation of the pelvis. At the same time, less tension in other parts of the back encourages a full range of seated movement.
The foundational shell of the upholstered work chair mimics the 3D Intelligent suspension. That gives the upholstered chair a healthy balance between support and freedom. An optional lumbar support for the upholstered work chair provides adjustment over a four-inch range.

Eco-Dematerialised Design
In creating SAYL, we used fewer materials in inventive ways to make the chair attainable for more people. Fewer parts and less material ultimately mean less cost and a smaller carbon footprint.
The ArcSpan seat base, arm structure, and tilt mechanism undercarriage are fused into a single, strong part, reducing the chair's material content and its visual "weight". The Y-Tower structure is sculpted and hollowed out to achieve the most strength with the least amount of material.
Controls are expressive and tactile. Just as important, they have been refined until only their essential forms remain.
We produce SAYL chairs on three continents to reduce the distance between factory and buyer.
SAYL chairs contain no PVCs and are 93 percent recyclable.

Attainable Design
As affordable as it is inventive, SAYL disproves the notion that a reasonably priced chair means offhand design and minimal ergonomics. From the beginning, our goal was to make a high-quality, beautifully designed, comfortable chair that lived up to our standards and was also affordable. SAYL is that chair.
