Abstract: The present disclosure provides a partition system comprising at least one pivot joint, each at least one pivot joint comprising: two pivot structures having partial circular cross-sections centered on a pivot axis, each pivot structure for engaging with a wall panel and permitting an engaged wall panel to pivot about the pivot axis; a linking structure extending between and joining the two pivot structures; and a stop member extending outwardly from a proximal end at the linking structure to a distal end spaced apart from the linking structure, the stop member limiting the range within which wall panels engaged with the pivot structures can pivot about the pivot axis, the partition system further comprising a plurality of wall panels, each of said wall panels comprising a pair of parallel tabs extending substantially perpendicularly from at least one end face of the wall panel, at least one of said parallel tabs having an end flange extending inwardly toward the other of said tabs, the end flange being adapt
