Sum: No adjustments required.
During our countless conversations with customers and users, we heard the same thing over and over again: chairs are too complicated. And then it hit us. What could be easier and more intuitive than automatic adjustments? So we introduced Sum. It’s more than just comfortable. It’s automatic.
Automatic Ergonomics
Sum work chairs and stools feature the AutoFittm automatic lumbar system. As users move, Sum's AutoFit lumbar system automatically adjusts and conforms to them, providing total back support exactly where it is needed. No adjustments, no guessing. This air displacement technology also ensures balanced pressure distribution in all seated positions, reducing pressure points and improving circulation.
The second component of Sum’s automatic ergonomics is Avatar 2tm, Sum’s balanced, weight-activated control. With Avatar 2, the user’s body activates the recline tension, so that each person automatically receives customized support in every tasking position. There are no knobs to find, no cranks to turn.
Sum was designed to fit 90% of the office population, from the 5th percentile female to the 95th percentile male. With this range of adaptability, everyone in the office can have personalized, comfortable support. They’ll be more focused and productive, no matter how many different jobs they’re juggling.
It all adds up with Sum.
