Adjustable seats are designed to enhance comfort and support for users by allowing them to modify the seat's position. This feature is commonly found in vehicles, office chairs, and some home furniture. Users can typically adjust the height, tilt, and sometimes the lumbar support to fit their individual needs. These seats often include mechanisms such as levers or buttons that make adjustments easy and quick. In cars, adjustable seats can improve driving posture and visibility, while in office settings, they help reduce strain during long hours of work. Overall, adjustable seats promote better ergonomics and user satisfaction.
