She showed the stools at at the Royal College of Art Show One in London earlier this month.
Here's some more information from Judith van den Boom:
Porcelain Seats Qing Zuo!
'Qing Zuo!, Please Sit down' project came from various corners this work period ‘07 in China, the combination of investigating and meanwhile focussing on material experiment. A dialogue between use and material, body language and sensation. Judith worked together with local crafts people in China to make wooden stools as well as documenting body language in sitting behavior.
A direct inventiveness that locals would use in building sitting objects became inspiration to have traditional techniques pushing the functional limits of porcelain. The seats are made by the designer in China in 2007 during a 3 month stay and finished in London into a final product. This series is a inspiration for a furniture line being launched later in 2009 where fore Judith will return to China in spring again.
