Occasionally throw out usable beds in a dishevelled state (6)
I believe the answer is:
tousle
'dishevelled state' is the definition.
(tousle can mean an unkempt mass)
I don't understand the remainder of the clue.
(Other definitions for tousle that I've seen before include "Of hair, rumple or disturb" , "Rumple, make untidy as with hair" , "Make hair untidy by ruffling" , "Dishevel (hair)" , "Ruffle (the hair)" .)
