Our mid-century modern Walnut Grove Tufted-Back Corner Sectional combines left- and right-facing sofas joined by a square corner. It features slim track arms, a tight back accented by a modern grid of button tufts, and plush cushions for supportive comfort. Each piece sits on a broad solid walnut sled base. In the fabric version, it comes with a total of three 20-inch square and three 18-inch square throw pillows.
