A floating floor system comprising: a plurality of panels each of the panels comprising: a panel body comprising a first edge and a second edge opposite the first edge; a first flange extending from the first edge of the panel body; a second flange extending from the second edge of the panel body; a snap-fit locking assembly comprising: a locking member protruding from the first flange and comprising a locking lip and a locking body, the locking lip comprising an undercut surface and a chamfered surface, the locking lip protruding from a side surface of the locking body in a direction away from the panel body; and a locking slot formed in the second flange; and wherein the snap-fit locking assembly is configured so that when the locking member of a first one of the panels is disposed within the locking slot of a second one of the panels, the first and second panels (100A, 100B) are vertically locked together via mechanical interaction between the undercut surface of the locking lip of the first panel and a locking surface of the second flange of the second panel, characterized in that the width of the locking member of the first panel is less than the width of the locking slot of the second panel thereby forming a deflection gap; and in that the locking member is resilient so that the locking member of the first panel is forced from a normal state into a deflected state whereby the locking member deflects into the deflection gap as the locking lip is inserted into the locking slot of the second panel and returns to the normal state when the undercut surface of the locking lip of the first panel comes into alignment with the locking surface of the second panel. a plurality of panels each of the panels comprising: a panel body comprising a first edge and a second edge opposite the first edge; a first flange extending from the first edge of the panel body; a second flange extending from the second edge of the panel body; a snap-fit locking assembly comprising: a locking member protruding from the first flange and comprising a locking lip and a locking body, the locking lip comprising an undercut surface and a chamfered surface, the locking lip protruding from a side surface of the locking body in a direction away from the panel body; and a locking slot formed in the second flange; and a panel body comprising a first edge and a second edge opposite the first edge; a first flange extending from the first edge of the panel body; a second flange extending from the second edge of the panel body; a snap-fit locking assembly comprising: a locking member protruding from the first flange and comprising a locking lip and a locking body, the locking lip comprising an undercut surface and a chamfered surface, the locking lip protruding from a side surface of the locking body in a direction away from the panel body; and a locking slot formed in the second flange; and a locking member protruding from the first flange and comprising a locking lip and a locking body, the locking lip comprising an undercut surface and a chamfered surface, the locking lip protruding from a side surface of the locking body in a direction away from the panel body; and a locking slot formed in the second flange; and wherein the snap-fit locking assembly is configured so that when the locking member of a first one of the panels is disposed within the locking slot of a second one of the panels, the first and second panels (100A, 100B) are vertically locked together via mechanical interaction between the undercut surface of the locking lip of the first panel and a locking surface of the second flange of the second panel,
