Now a Crate and Barrel classic, its pure 1960s aesthetic is scaled deep so you can sit firm and upright, but also slouch back in comfort. Well-suited to make a great impression, the menswear-inspired fabric tailors Petrie's sleek, boxy cushions and slim track arms with heathered color and soft texture. Easily create a custom sectional for your unique space by joining the left arm corner sofa with companion pieces from the Petrie Sectional Collection. The Petrie Midcentury Left Arm Corner Sofa is a Crate and Barrel exclusive.
