Suspension Upholstered
Work Chairs Body of Comfort
For over 75 years, we’ve immersed
ourselves in the art and science of
seating. SAYL reflects that passion
in the inventive ways it supports
the body.
The chair’s distinctive
Y–Tower ™ structure
provides the connection
points for the suspension
back. It is the foundation
of the chair’s distinctive
arc, which mirrors the
curvature of the spine.
The ArcSpan ™ along with
the arm structure and tilt
mechanism are fused into
a single triangulated part.
Its strength reduces the
chair’s material requirement
and weight.
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.
The back supports the
transition area from the
thoracic to lumbar areas and
again between the lumbar
and sacral areas. “Hinge
points” allow these areas
to flex and adapt to each
individual while supporting
the healthy, forward rotation
of the pelvis.
Support is molded directly
into the 3D Intelligent back
material. That support is
greater in areas that need
it—sacrum, lumbar, and
spine—lesser elsewhere for
freer movement.
An optional lumbar support
for the upholstered work chair
provides adjustment over a
four-inch range.
Height-adjustable arms move
vertically over a four-inch
range. Fully adjustable arms
move vertically, as well as
front to back and inward and
outward.
