A divider assembly for dividing a space into physically separated sub-spaces, comprising a support structure for fixing a divider in an upstanding orientation thereby dividing said space in which said divider is placed, the support structure includes a body defining a main axis, a holder provided on first side of the main axis and along length of the body for holding the divider in said upstanding orientation, and a coupler provided on second side of the main axis and along length of the body for direct coupling with another said support structure, such that said divider assembly is expandable into adjacent space for creating further separated sub-spaces.
