Arum is an armchair designed by Archirivolto Design and manufactured by INCLASS for use in public or private spaces. With a polypropylene design, the user now enjoys more customization options in new colors. Its design is embracing, fluid, and clean. All joints are invisible, which is an aesthetic improvement in this type of armchair. The armchair is available with a fixed upholstered seat or a removable upholstered seat.
