Using your Christopher Knight Home® Pema 8 - person modular outdoor sofa is a breeze. First, assemble it according to the included instructions. You can arrange the four seat sectionals in a half - circle or even form a full - circle lounge based on your space and preference. When using the sofa, enjoy your outdoor gatherings with the comfort of the water - resistant cushions. However, remember that the cushions are not waterproof, so keep them away from direct submersion in water. For maintenance, simply wipe the cushions with a damp cloth as they are covered in non - porous material. The polyethylene rattan is durable, but you can clean it occasionally with mild soap and water to keep it looking great. If you plan to store the sofa during off - seasons, find a dry place to protect it from harsh weather conditions.
