This is a new outdoor modular sofa set. We recommend you use an upholstery cleaner and bring your cushions indoors when not in use because they are not fully waterproof. This item is a perfect garden dining and lounging set. Each seating part is an individual module and the set is made up by simply putting the modules together. They do not clip together but instead sit next to each other to make either the U-shape or L-shape corner unit. You can also create a large square sunbed using your modular units. The rattan is waterproof and can withstand wet weather, but we highly recommend purchasing a cover for long periods in wet damp weather.
