At Wilkhahn, after having a quick look around, I noticed this stool at the high table. Although not meant to be part of their show I really liked the simple idea. The stool is height adjustable and has a weighted spherical base to aid comfort. The weighted bottom creates a very stable seat that can be used on any surface. Not the main intended focus at Clerkenwell but certainly caught my attention and was very comfortable to sit / perch on.
