To use this duvet, simply place it on your king - sized bed. It's great for summer, so you can enjoy a comfortable and cool sleep. When it comes to maintenance, it's best to follow the care label instructions. Usually, you can machine - wash it on a gentle cycle with mild detergent. Make sure to dry it thoroughly, preferably in a well - ventilated area. Avoid using harsh chemicals or bleach as they may damage the natural cotton. Also, don't wring or twist the duvet during the washing process to keep its shape intact.
