Using this duvet cover set is easy. First, zip up the hidden zipper and insert your duvet insert. You can use it all year round to keep you comfortable. When it comes to cleaning, it's best to dry clean it for the best results. But if you want to machine wash it, use cold water and a gentle cycle. Only use non - chlorine bleach when it's really dirty. Tumble dry on low and iron on the lowest setting if there are any wrinkles. Keep in mind that the inserts are sold separately, so you'll need to buy them if you don't have one already.
