Called Matrioshka, the wooden storage units all fit inside the large orange armoire. Pull out the cabinets as and when you need them, or use them all from the off. They have a pretty 60s vibe about them that may or may not be to your taste, but they're damn practical regardless.
While they made their debut at the Milan Design Week earlier this year, they're now to be manufactured by SCSplus and Ergomade. Sadly there's currently no word on pricing. More here.
