Made use of a sofa (3)
I believe the answer is:
sat
'made use of a sofa' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sat that I've seen before include "Rested" , "nearly half a day" , "Was in session" , "Took a seat and posed for a portrait" , "Used a chair" .)
