If you currently own a "Soft Rail" waterbed system, and need to replace your cover system, or the foam rails, we no longer manufacture the Soft Rail System parts. In order to replace components from this system, you will need the F8SET rails, plus a new zip-on mattress top and zippered sidewall  (border and bottom assembly). You will need all 3 components to complete this process.  Choose one of the zip-on mattress tops below along with the rails and zippered sidewall.
