A playyard floor support frame includes a rail mount (32) and at least two floor support rails (36, 40). Each floor support rail (36, 40) includes a stationary end piece (134) mounted on an inner end pivotably coupled to the rail mount (32) to enable each floor support rail (36, 40) to be moved relative to the rail mount (32) about a pivot axis (120) between an erected configuration adapted to support a floor mat on the floor support rails (36, 40) and above the rail mount (32) and a collapsed configuration adapted to facilitate storage of the floor support frame, and a rail lock apparatus (62) coupled to the rail mount (32) and configured to latch onto the stationary and piece (134) of selected floor support rails (36, 40) and to block pivoting movement of the selected floor support rails (36, 40) relative to the rail mount (32) about the pivot axes (120) to lock the selected floor support rails (36, 40) to the rail mount (32) upon movement of the floor support rails (36, 40) relative to the rail mount (32) to the erected configuration.
