You can certainly wash a boppy. I washed it in the washer and I think I laid it out to dry. You could stop the rinse/spin cycle and flip it once to try and maintain the perfect shape. The website isn't easy to use, but call Boppy (like I did) and they will walk you through it AND tell you where on the website to look for washing instructions.
