IVY is a new stackable shelf system designed by Thomas Bernstrand for Swedese. The shelf’s can be stacked in three different ways, straight up, left or right. Stacked to the left it will lean left, stacked to the right it will lean right. When alternated it will level out. If you have five pieces you can stack them in 81 different ways. IVY is made of clear-varnished pinewood or painted ash in white or black.
