Inflated Mylar Balloon Stools Won’t Pop When You Sit on Them

Designed by Oskar Zieta and available from the Gessato design store, the Plopp metal stool has the appearance of an inflated mylar balloon. It’s nobody’s birthday though, the stools are actually constructed of welded steel sheets that have been industrially inflated using a process developed by Zieta known as “free inner pressure deformation”.
