The way that this chair folds and has a handle makes it look like it is very easy to move out of the way without taking up almost any space. However it would by quite difficult to do the same thing with a stool and it doesn't looks like it is very stable.
This is a genius idea. A chair/ bench that can transform into a table, or both! This would be excellent to use in a smaller space where having multipurpose furniture is key to a functioning space. Or an outdoor space.
