Feel free to toss your Casper Pillow in the washer/dryer - it will come out ready for any sleeping position, tumble dry after tumble dry.
For the Original Casper Pillow:
Step 1: Unzip the outer pillow and remove the inner pillow
Step 2: Zip the outer pillow closed
Step 3: Place both pillow layers into your washing machine (preferably a front-loading one)
Step 4: Wash with cold water and a mild liquid detergent
Step 5: Tumble dry on low with dryer balls (or clean tennis balls)
We recommend washing your Original Casper Pillow every 3-6 months—two pillows on average per load.
