So, was just wondering if anyone here has different branded washer and dryer stacked on top of eachother - I'm looking at heat pump dryers and would ideally like to stack it on top of the front load washer. Both are the same depth and width - but as I understand it you have to get the same brand to make a stacking kit work, because just sitting one on top of the other usually ends up with the top one on the floor eventually?
