Forget pictures or videos – there may be no better way to pay tribute to your cats than by creating a piece of furniture in which they come first, like this crafty sofa for kittens that can also be occupied by humans.

Korean designers Yongjeh Park and Kangkyoung Lee collaborated on the design and creation of this prototype, and their process is as interesting as the product, as illustrated in the sketches and construction images above.

The tunnel is the driving force behind the design, starting on the floor with a mid-tube exit along the back (to peer over a person’s shoulder) and a terminal entry (where a drooping hand is most likely to be poised for petting a head).
