I'm talking about the Componibili, of course!
It's seriously the most adaptable piece of furniture in all the land. I've used them in shoots for kids rooms, as bedside tables, and recently in a bathroom and you can't go wrong.
Just to recap, it's the Componibili designed by Anna Castelli Ferrieri for Kartell and it'll set you back around $200 from Top 3 By Design. Buy it, then wonder how you lived without it.
