Used Allsteel Sum Chair

Sum's AutoFit lumbar system uses air displacement to automatically support the user's back, reduce pressure points, and improve circulation.

No adjustments required.

What if all you had to do was sit? and without touching a knob or lever, your chair provided ideal ergonomic positioning by adapting itself to your weight, size, and working position?

Introducing Sum. An office chair that's more than just comfortable, but automatically creates a perfect seating fit and posture for 90% of human shapes and sizes. Sum is made with several proprietary design features that provide completely customized, totally foolproof support for anyone who sits down. And all without training, tuning, or trying to find controls and figure out which does what.
