Do I need the terrycloth covers you can buy, or will the foam layers (6" king base and 4 seperate 1" king toppers layered to our liking) stay put with just the cuddle bed?  Doesn't it go around the bottom edges, and won't the latex be OK sitting directly on the flat frame?  I could always place a clothe layer between it and the base, but I want to try the cuddle bed anyway, and that should hide the foam visually.  Sheets cover it all anyway.

 SleepEZ sell the same cover they use in their mattresses for $249, a terrycloth cover is $80, but if I have the cuddle bed anyway, do I need more?

And whats the deal with terrycloth anyway, is it just cheap and comfortable?  Would I even feel the difference with a cuddle bed?  Would I ever need the expense of the SleepEZ, which looks very finished (just like a store bought mattress), if I use the cuddle bed, or is it just a nice touch?
