جلس (Sitting) is a common posture where a person rests their body on a surface, typically a chair or the ground, with their weight supported by their legs and buttocks. This position allows for relaxation and is often used during meals, conversations, or while working. In many cultures, sitting is associated with social interactions and gatherings. For example, in Arab culture, sitting together can signify hospitality and friendship, often accompanied by sharing food and drinks. Proper sitting posture is important for health, as it can affect spine alignment and overall comfort.
