Using your new sofa bed is a breeze. When you need to convert it into a bed, just find the pull tag in the center and give it a gentle tug. The mattress will fold out to a full - size bed supported by a metal frame. When you're done, fold it back up to use it as a 3 - seater sofa. As for maintenance, since the cushions are removable, you can easily take them off and clean them when they get dirty. Keep the sofa away from direct sunlight to prevent the fabric from fading. When assembling, follow the instructions carefully. If you have any questions, don't hesitate to contact our customer service.
