If you like a little more room in your sectional, the Vela Outdoor Sofa XL Left Arm Section is there to provide it. This modular component of the Vela sectional sofa is nearly 2 feet longer than the standard Vela Left Arm Section. It includes the same angular base made out of matte white polyethylene and sharply tailored--yet soft-feeling--cushions in matching white all-weather vinyl.
