As far as the standard hard plastic mono block chairs are concerned, they are really standard means of alternative chairs in use today. We often see then in events such as parties or even take the place of the usual dining chairs today. But while their main purpose of providing seating is there, you can tweak it a bit to come up with a one of a kind design as well.
Add a little bit of leather upholstery and the whole design will be changed in an instant. It is really something that can mislead people into thinking where this chair came from. Well you can always I just designed it myself. Now who would get the credit right?
