This patio sofa works nicely as a sectional piece thanks to its single armrest on one end. Full of clean lines and sleek modern style, it's made from rust-resistant aluminum with a muted flint finish. The seat and back cushions are spun with a polyester-blend fabric and filled with foam to provide just the right amount of support as you relax outside on your porch or deck. The cushion covers are also removable: Just unzip them for an easier cleaning experience by tossing them into the washing machine.
