Vertically channeled upholstery wraps the arms and back, breaking up what would otherwise be a boxy silhouette with a subtle rhythm of lines. The seat pads are generously cushioned, and the fully upholstered frame keeps the piece looking finished from every angle, which matters in a guest room where the sofa is rarely against a wall. A low-profile wood plinth base anchors it and gives a warm structural counterpoint to the upholstery above. At 81 by 37 inches, it converts to a sleeping surface without losing its daytime tailoring. Four units minimum.
