Smart design. Easy comfort. The Calder Modular Sofa delivers sink-in softness with a frameless, foam-based build that feels as good as it looks. Made entirely from dense foam, memory foam, and fiber fill—no frame, no tools—this modular design ships vacuum-sealed in space-saving boxes and expands fully within 24 hours. With wide arms, soft back cushions, and a grippy base that stays in place, it’s lightweight, low-profile, and endlessly flexible—perfect for compact seating or built-out layouts.
