A tray substrate (100) of a flooring system comprises : a tray substrate surface which is an upward facing horizontal surface; a tray substrate bottom with a padding attached to the tray substrate bottom; a plurality of vertical tray edges which protrude upward and extend around a perimeter of the tray substrate surface; a plurality of tray substrate edges defining an outsider perimeter of the tray substrate; the tray substrate edges having a plurality of upward tabs (200) and a plurality of downward tabs (300), wherein the upward tabs (200) have a surface (210) and a valley (220), and the downward tabs (300) have a surface (310) and a lip (320). In order to provide a narrow gap between two interconnected tray substrates, a portion (330) of each downward tab (300) is recessed under the upward facing horizontal surface. |
