Korean designer Seungji Mun created this concept for a feline-friendly sofa. Simply called the Cat Tunnel Sofa, it integrates a play tube for kitties into the design of the sofa structure. I think it’s pretty brilliant and I have some foster kittens right now who would go out of their minds for this.
As a concept, it’s intriguing, but I do think there are some practical issues that need to be addressed. The number one concern I have is cleaning. Yes, there’s an opening on top, but there are still long stretches of tube that I’m pretty sure will be christened with a hairball or two almost immediately upon introduction. How are you going to clean that? Also, I have a rule that there are no places in my house where my cats can go where I could not reach them in case of an emergency (or an unwanted trip to the vet), so this would need some modification to work for me, but I absolutely love the basic idea.
