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. Sleek, boxy cushions and slim track arms look elegant and polished thanks to its supple, luxurious leather that will develop a beautiful, natural patina over time. Here, we've paired the leather left arm corner sofa and right arm loveseat; you might also choose to add companion pieces from the Petrie Leather Sectional Collection. Petrie Leather 2-Piece Corner Midcentury Sectional Sofa is a Crate and Barrel exclusive.
