I'd say concrete blocks, but depends how often you need to clean, right?
They are cheap.. you can make your own if you want.. Make the forms
and mix it yourself. Strip the boards and add whatever you can wash.
Indoor outdoor carpet.. Same with premade blocks, if weight is an issue
Stack, test, then cover
