originally purchased to put the feet of my dryer to replace a stacking kit, I finally opted for laying at the feet of my washing machine to soften even the tiny vibrations of new appareils.J 'was able to put my dryer above the washing machine without the risk of landslides because of it exempt from vibrations during the spin cycle. Moreover, the vibrations could damage a term mechanical operation of both units and also crack the tiles. So triplication!
