PRODUCT INFORMATION
The Seam sofa by Prostoria is a modern designer lounge sofa defined by the purity of a single sculptural volume—no loose cushions, no extra layers, just one continuous form built for comfortable, supported sitting. A dramatically deep backrest and armrests sweep inward in a smooth arc, creating an ergonomic cradle that feels both structured and soft. Precise, visible stitched seams trace the geometry and “draw” the silhouette, turning a functional detail into the collection’s signature line. Minimal yet expressive, Seam brings a quiet, iconic presence to refined residential interiors and performs just as confidently in public and contract spaces—from hotel lobbies and waiting areas to offices and reception lounges.

GALLERY
A single sculpted volume—no fluff, no clutter, all comfort. The sofa that feels tailored, not piled on. One continuous curve. One iconic seam. Clean geometry, surprisingly cozy seat. A sweeping arc that pulls you in—and holds you there. Minimal on the outside, deeply supportive inside.
