Very sturdy and doesn't slip on the wood floor, purchased a pet mat from Wayfair as well (hasn't arrived yet) thinking we would need it for splash protection but there is a rubber 'gasket' around the rim of the metal bowl that prevents it from moving while our dogs drink from it so there is very little spillage and no metal on metal noise that I sort of expected?  The reason for the 4 stars is the height (yes, I should have verified the details more closely) but simply chose "medium" for our two Labrador sized dogs.  It's a little short for them but they haven't complained, turns out it's the perfect height for the cats too !
