The Active Sitting Office Chair.
This is the backless, tilting office chair that strengthens one’s back and promotes a healthier, active sitting style. The pedestal style chair leans slightly in any direction, forcing sitters to engage their core muscles to maintain a proper, upright sitting position. Actively working the core while you sit helps strengthen stomach and back muscles while the lack of a backrest discourages slouching, a major cause of back discomfort. Unlike traditional chairs that can restrict blood circulation in the legs, the rounded seat sides do not exert contact pressure on the back of the legs, reducing muscle fatigue. The chair is height adjustable via the pneumatic cylinder post, it has a 14"-diameter padded vinyl seat, and a sturdy stamped steel base with a black vinyl cover. 15" Diam. (14 1/2 lbs.)
