Meticulously crafted from a blend of polar fleece and high-quality polyester upholstery fabric.  The polar fleece side offers self-warming coziness, while the soft polyester side provides a cooling option. On the inside, thick wadding features a 6 x channeled cushion, securely holding the Snoozafill in place during washing and ensures your pet enjoys a comfortable nap. The entire bed is machine washable.
