The SILLA40 Upholstered Chair, designed by Isaac Piñeiro of Nadadora, marks Sancal’s 40th anniversary with a unique concept. This collection features four distinct backs, each reflecting a pivotal era in furniture design, while maintaining a consistent structure. The R20 back draws inspiration from Marcel Breuer’s Cesca chair, while the R30 pays homage to Scandinavian design, particularly Alvar Aalto’s 69 chair. The R40 variant celebrates the organic forms of the mid-20th century, reminiscent of Charles Eames’ LCW chairs. The R70 embodies postmodern influences, inspired by Ettore Sottsass’ Synthesis45. Ideal for dining tables, conference rooms, and cafés, these ergonomic, stackable chairs offer durable seating with a modern design. The chair features an upholstered seat and back, with ash or metal feet, and customizable fabric and wood finishes.
