Inspired by the nomads of northern Paraguay it allows the user to sit in a relaxed manner, but with no seat or backrest, simply a strap of fabric.
It offers a really rather clever solution for when chairs are in short supply, or impractical to carry around (think lunch in the park, sitting down at a festival, reading on the beach), and having a design approach verging on “extreme minimalism” you can carry it around with you wherever you go. This leaves your hands free “to operate your iPad” (read a book, eat a sandwich, or something else mundane).
It’s even been endorsed by medical professionals as “there are no more risks involved than when using a conventional chair”. Excellent, get one here.
