Yes, it is machine washable. We decided not to use memory foam for our pillows for this specific reason, because it is so dense, memory foam takes much longer to dry, is hotter than traditional foam and holds sweat in. Travel pillows that use memory foam cushions can’t be machine washed, and that makes no sense to us. When you travel, you are seeing the world, and naturally... things you wear and use often will get messy. Trust us, you want to be able to machine wash the thing you sleep with and put your head on. However, we do suggest air drying our pillows to increase longevity of your foam cushions, since it is still foam and it can still slowly deteriorate with over washing/drying
