I will try to help you with this.
First I‘d like to know if by „replicate“ you mean that you‘re trying get some online functionality to work or if you are trying to apply the behaviour of the chairs onto the cube.
Currently you have two hardcoded variables, it seems, „Conj1“ and „Conj2“. In order for the Cube to change into a chair and then back into a Cube again, I‘d assume one of these variables have to reference the cube. Have you tried that?
