Using this Christopher Knight Home® Pema Outdoor 4-Person Sofa Set is a breeze. First, find a nice spot in your outdoor area for it. Then, follow the included instructions to assemble the four seat sectionals. You can arrange them in a full - circle lounge or in a semi - circle based on your preference. When it comes to using the cushions, just sit back and relax on them. But be careful, as they are water - resistant and not waterproof. So, if it starts to rain, it's a good idea to cover them or bring them indoors. For maintenance, the cushions are easy to clean because they are covered with a non - porous material. You can simply wipe them down with a damp cloth. As for the polyethylene rattan sofa, you can clean it with mild soap and water occasionally to keep it looking great. Also, make sure to check the assembly parts from time to time to ensure they are still secure.
