We're thinking of setting up the washer & dryer in a new place, plonking the washer in a drip tray, on top of a mat to cut down vibration, and with a stacker kit so the dryer can go on top.
Will the vibration mat still work under the tray or should it be in the tray? And are stacker kits less flimsy than they look?
I can't go round people's houses because lockdown :(
