In many families, friend groups, and offices, some seats seem to have an owner, even without any formal division. The recurring choice of the same chair may be linked to the need to create familiarity, reduce uncertainties, and maintain a certain sense of control.
The habit can also take on a territorial component. Over time, a particular seat comes to be perceived as an extension of personal space. Therefore, finding another person in that spot usually causes discomfort, even though any chair serves the same function.
The chosen position can also reflect the role played in the group. Sitting at the head of the table facilitates more central participation, while occupying a side or edge allows for more observation and less exposure.
This does not mean, however, that a chair is enough to define personality. The preference can simply be explained by comfort, lighting, proximity to someone, or the ease of getting up.
