These objects are nothing to worry about. They are from the ZEN family designed and manufactured by Mago Urban of
Barcelona and exclusively available from Public Spaces. Is it a seat , a bench or even a piece of art. Well, they are what you want them to be ! They are a much more interesting prospect than simply a bollard to stop cars parking and may be used as a spontaneous form of seating, on a piece of grass where people gather.
