A Stick Stool, Wrap Chair, Poster Chair or Graffiti chair?
Dutch designer Gerard de Hoop of Dutch Design partnership Huting & De Hoop has baptized this seat as Stick Stool, because you can stick a poster to it or wrap it in a poster or a piece of cloth. On their website the same chair is shown, decorated by a graffiti artist and baptized Graffiti Stool.
I doubt their use of the word stool is correct English as the English Chair Wiki says:
A chair is a piece of furniture for sitting, consisting of a seat, a back, and sometimes arm rests, commonly for use by one person. Chairs also often have four legs to support the seat raised above the floor. Without back and arm rests it is called a stool.
This seat has a back. so it is a chair and not a stool.
Making promotion for the Dutch Queen here is a nice extra.
