Sleepgram Sheets aren't your average bedding purchase, and they need to be cared for properly. Whether or not your Sleepgram Sheets come with their own set of washing instructions, there are a few general guidelines to keep in mind. A light detergent and a soft cycle are best for washing Sleepgram Sheets because they shrink more than cotton sheets. To prevent pilling, avoid washing your Sleepgram Bamboo Sheets with any material having zippers or hooks, including towels or blankets. After washing, air dry or use a low heat setting on a clothes dryer.
