How do I clean my Boppy® pillow?
Most Boppy products are machine washable and dryable. Wash your Boppy pillow in cold water on the delicate cycle by itself. Dry your Boppy pillow on low heat. We also recommend throwing a sneaker or tennis ball (wrapped in a pillow case) in the dryer to help the Boppy pillow keep its shape.
There is a lot more Boppy info on the link as well.
Happy Holidays,
