We've never had a tumble dryer before so we searched around for stacking options and this came up on AO. You need to measure your washing machine and make sure you're purchasing a tumble dryer the same size. Once it's all strapped in it's solid. You need someone strong to lift the tumble dryer on top of the washing machine too, particularly if it's in a confined space which is usually the case in a utility. Would definitely recommend. Excellent service from AO, as usual.
