Sum™ is designed to help workers keep their eyes on their work
and connected to their task. It’s an ergonomic chair that fits
90% of the worker population. Sum’s unique design knows
exactly how and where customized comfort and support is
needed for each user, and provides it responsively. Quality,
intuitive functionality, and timeless style. It all adds up with Sum.
POSTURE CONTROL SYSTEM —
Avatar 2™ ensures the chair back and seat remain positioned
for optimal ergonomics and comfort, while maximizing the
back-to-seat ratio. This motion expands the torso and allows
for better circulation while preventing fatigue. The tilt lock
allows the user to secure the chair in an upright position, or
to tilt freely.
PROPORTIONAL CONTROL SYSTEM —
AutoFit™ uses air displacement technology to provide
customized back support. Air displacement technology
fills the space between the user’s back and the chair back,
automatically adjusting from top-to-bottom and side-to-side
to provide optimal lumbar support. The result is lasting
comfort throughout the workday.
Pneumatic Seat Height Adjustment
Regulates height of chair relative to the floor.
• Standard 5" of travel accommodates average or tall users.
• Optional 31⁄2" of travel keeps chair closer to the floor for
shorter users, allowing all models to meet BIFMA G1-2002
solutions for VDT users.
Seat Depth Adjustment
Allows seat support to travel front-to-back and lock within a
3" range.
With Sum, there’s no guessing about the best position for
lumbar ergonomics. It just happens. Sum’s proprietary* AutoFit
design uses air displacement to find exactly where each back
needs the most support, and then provides a customized fit.
As you move, Sum’s conforming back adjusts top-to-bottom
and side-to-side to ensure balanced pressure distribution in all
seated positions, even the most relaxing recline. The result is
lasting comfort throughout the workday.
A layer of impermeable SaranexTM film surrounds AutoFit for
lasting durability.
