What are corner tiles, border tiles and center tiles?

Our 3/8" Tight-Lock Tiles are just like the pieces of a jigsaw puzzle, so just like a puzzle, our tiles also come in corner, border and center pieces. Corner tiles are designed to be used in the corner of your floor, with 2 flat edges to go right up against your wall. Border tiles go along the border of the floor and have 1 flat edge for the side that touches the wall. Center tiles are used in the center of the floor, and have interlocking edges all the way around with no flat edges.
