Story
A heart drawn in volume
Soft Heart turns its name into the armchair's outline: two rounded upper lobes meet at the centre, while a curled extension opens from the lower edge. Ron Arad developed the design for Moroso in 1991.
Spring Collection construction
The continuous upholstered volume is made possible by cold-injected polyurethane around steel. Unlike the separate Spring modular sofa by Patricia Urquiola, this Ron Arad armchair belongs to the 1991 Spring Collection and carries a fixed cover.
