Perspectives Smart Object

Hi all!

I know how to work with smart objects and mock ups, in different ways, but I can't find a tutorial where they explain this problem:

I have a pattern, and I want to do a mock up where the pattern covers a bench. Imagine that the bench is like a cube, and I want the pattern to cover all showable sides without breaking. 

How do I do that, so the perspective looks right? Can I make all the sides of the cube-bench individually and then somehow put the layers together, so when I do a smart object - the pattern continues and covers all the sides with the right perspective? Or is there another way?

Thanks!
