The ActiveGuard Mattress Liner should be fine to use on a waterbed mattress as long as you select the correct size for your bed. We would still recommend using a mattress pad underneath the ActiveGuard Liner, and of course a fitted sheet on top of it when making the bed. Please keep in mind that we do not recommend the ActiveGuard as the sole treatment for existing bed bug infestations.
