Sitting is not new. What is new is how consistently we do it, and how little the position changes across a day. Screens, vehicles and desks have made one configuration of the body the default for work, study, commuting and rest alike.
Most ergonomic thinking responds to this by optimising the static position: better lumbar support, better cushioning, better adjustability. That work matters. But it accepts a premise worth examining — that the goal is to hold a good position rather than to change position.
At BAID we are interested in the second path. If the seated posture itself varied slightly and periodically, the body would be asked to adapt rather than to hold. That is a mechanical question before it is anything else, and it is the question our development work is built around.
