  • Care & Use

    Washing the cover:

    • Washing the outer cover before first use is optional.
    • Cover zips off and goes right in the washing machine.
    • Be sure to leave the cover unzipped for best results.
    • Wash on cold with a mild detergent.
    • Tumble dry on low heat. Dry thoroughly. DO NOT hang dry.
    • Wash the outer cover as often as you like.

    Washing the encasement:

    • Clean encasement only if soiled.
    • Unzip and remove from core.
    • Zip fully closed prior to wash + dry.
    • Machine wash in cold water with detergent.
    • Wash together with outer cover for a balanced load. Wash without any other laundry.
    • Dry immediately in dryer on tumble dry low heat setting, allowing to dry thoroughly. DO NOT leave damp from wash; DO NOT hang dry.

    TIP: The encasement is made with natural Viscose material which may develop an odor if allowed to remain damp (like a wool sweater). To refresh, add 1/2 cup baking soda to the wash
