Abstract
A waterbed mattress liner tray includes a bottom wall, headwall, footwall and opposite sidewalls integrally formed into an open-topped water retaining tray. Each sidewall is formed with a spring portion which is compressible under a downward load but which is spring biased to expand to its normal height upon removal of the downward load so as to provide the support characteristics of a soft side waterbed. The bottom wall may be contoured to form riser sections for varying the support for different body parts of a sleeper. Longitudinal channels extend across the riser sections to afford drainage thereacross.
