Alcove is a Sofa System by Ronan & Erwan Bouroullec for Vitra. Each element is formed of a powder-coated metal frame, upholstered with fabric, and a structure in MDF panels. The seat is padded with polyurethane foam; while the backrest and armrests are powered with feather padding. The fabric upholstery is removable.A sofa which can turn into a "room within a room": this idea inspired Ronan and Erwan Bouroullec to create Alcove Collection. The sofas are characterized by the ergonomic shape which hugs the figure and provides comfort and relax. The Alcove Collection is perfect in every context. It is possible to choose also the pouf or the additional cushions.The cushions set includes two armrest cushions and two backrest cushions.
