Replacement Waterbed Mattresses

Experience a revolutionary feel with our replacement waterbed mattresses. Designed to provide optimal support, the waterbed bladder within these mattresses allow you to customize the level of wave control according to your preferences. Available in various sizes such as super single, California queen, and California king, these mattresses are perfect for fitting your wooden waterbed frame. Additionally, we offer an extensive range of waterbed bladders, including shallow fill, midfill, and deep fill options for softside waterbeds. Please contact us directly for assistance, as fitting these bladders can be challenging due to the non-standardized innards of the beds.
