To use this doona, simply place it on your king - size bed. It's great for summer when you want a bit of extra warmth. When it comes to cleaning, you can machine - wash it on a gentle cycle with mild detergent. Make sure to dry it thoroughly on a low - heat setting. Store it in a cool, dry place when not in use. Avoid using harsh chemicals or bleach as they can damage the bamboo fill and the cotton japara cover. Also, don't wring or twist the doona during cleaning to keep its shape intact.
