Oslo's plush 3-Seater offers blissfully versatile comfort along with its crisply geometric lines. Perched on reedy legs, the sofa beckons with a Kvadrat-clad expanse over a cast-foam shell with a steel inner frame. Much-lauded design duo Anderssen & Voll say they wanted the seating to have a friendly Nordic vibe, "an embracing and rounded softness." Produced by Danish house Muuto, the Oslo series is crafted on the west coast of their native Norway to exacting standards.
