Sofa frame (5)
I believe the answer is:
couch
I believe this is a double definition.
'sofa' is the first definition.
(synonyms)
'frame' is the second definition.
(framing or couching something in certain terms)
(Other definitions for couch that I've seen before include "Long seat; grass" , "Sofa or settee" , "express" , "Upholstered seat for more than one" , "Grass; reclining seat" .)
