Is it a storage unit or cat playground? Why not both? Featuring a laser-cut, cold-rolled steel frame with a matte powder coat finish and multifunctional cubbies, it’s as easy to stow things away as it is to climb. Just don’t put your things in the bottom cupboard – it features a hidden litter box, so things could get messy. Available in multiple colourways. From $2500, at Cofo Design.
