Water Proof Mattress Protector
To protect your mattress, we suggest using a waterproof mattress protector between the Chilipad Pro pad and mattress. Not only because condensation may occur under the pad in some high-humidity environments, but also because the protector extends the life of the mattress.
Additionally, consider contacting your mattress manufacturer for guidance to ensure using other products on top of your bed does not void your mattress warranty.
