A hydrotherapy mattress assembly which includes an air-over-foam core, a base for receiving the air-over-foam core, and a top cover overlying the air-over-foam core. The top cover provides a patient support surface and includes a drain trough. The drain trough is coupled to a drain which extends through the air-over-foam core and the base, so that liquids can be drained from the patient support surface.
