Caution, inconvenient!
From 13.05.2026
Until 01.11.2026
Step out of your comfort zone — Caution, inconvenient! Come and sit on a chair that won’t let you forget you’re sitting. Walk across a floor that ripples beneath your feet. Comfort is not something we should take for granted. It's science, design, and thousands of years of human experience compressed into a perfectly shaped step you have never even noticed.
