Using your Christopher Knight Home® Oana 3 - Piece Dark Grey Outdoor Sofa Set is a breeze. First, assemble it following the instructions in the package. Once it's set up, arrange the seating according to your space and needs. You can put the twin sectional end pieces and the armless component in different combinations. For cleaning, remove the cushions and unzip the covers. Wash them as per the care label. The sofa made of acacia wood doesn't need much maintenance, but you can wipe it down with a damp cloth regularly. In case of heavy rain or extreme weather, it's a good idea to cover the sofa to keep it in top condition. When you need to store it, disassemble it easily and find a dry place to store all the parts.
