Using this U-shaped outdoor sofa set is a breeze. Just assemble it following the easy - to - follow instructions. All the hardware and components are labeled, so you won't have any trouble putting it together. Once it's set up, you and your friends or family can sit on the thick cushions and backrests to relax and socialize in your garden, backyard, or balcony. When it comes to maintenance, since the frames are made of anti - rust aluminum, you don't have to worry too much about rust. But it's a good idea to clean the sofa set regularly with a mild soap and water solution. If there are any spills on the cushions, clean them up as soon as possible to keep them looking nice. Also, in harsh weather conditions like heavy snow or strong storms, you might want to cover the sofa set to protect it. And that's all you need to know to make the most of your outdoor sofa set.
