Zip-up chair by Kim In-bo looks like a sack of white rocks when its not a chair. But, in case you are too tired then you might want to zip it down to sit on it. When you do so, all you have to do is turn down few swabs to make it worth sitting on. It can not only make you sit, but can also be used as a small table and a mattress (when it opens, below) when it Is not fulfilling its duty of a chair. Originally designed as a functional piece of furniture for small spaces, it can also be used in sophisticated interiors. With ample coolness, it also has a tinge of sophistication.
