Description

Office chair convenient for leg support Technical Field The utility model relates to the technical field of office chair devices, in particular to an office chair convenient for supporting legs. Background Office chairs are various chairs equipped for convenience in daily work and social activities. OfficeMate office partners divide office chairs into a narrow sense and a broad sense, wherein the narrow sense office chair refers to a backrest chair for a person to sit on when doing a tabletop work in a sitting posture state, and the broad sense office chair refers to all chairs used in offices, including office chairs, middle office chairs, guest chairs, staff chairs, conference chairs, guest chairs, training chairs and the like. In order to make the person lean on the office chair more comfortable, leg supports are sometimes mounted on the bottom of the office chair.
