The Dream sheet sets are amazingly soft, high-end sheets made out of pure viscose from bamboo. Certain bedding only gets better with wear & age. And these Yala Designs’s sheets not only get better with wear and age, they keep their softness for years. Believe it or not, the more you wash and use them, the softer these bamboo sheets become. What’s more, this manufacturer does not add chemicals or anti wrinkling agents. Like in real life, some wrinkles are simply a part of the experience. Once you have had these sets, you will never want to go back.
