Some mattress material (4)

Ross

I believe the answer is:

foam

(Other definitions for foam that I've seen before include "Boiling bubbles" , "Bubbles on liquid" , "At the mouth, this may mean madness or extreme anger" , "Mass of small bubbles" , "Lather, froth" .)

I've seen this clue in the USA Today.
