No, it’s not a strap—it’s a chair dammit. A really awkward and potentially uncomfortable chair, but a chair nonetheless.
Chairless was designed by a high-end German furniture company called Vitra, although it was inspired by a similar strap used by Ayoreo Indians. According to Vitra, it’s a “seating device for the modern nomad.” Part of the proceeds from each sale go to support the “Foundation for Paraguayan Indian Communities”.
Amazingly, the strap sold out in its first run and won’t be available again until June. Of course, you could save a few bucks and tie together some rope or re-purpose the shoulder strap of an old bag and achieve the same effect.
