Soft as fur, okay? (8)
I believe the answer is:
passable
'okay?' is the definition.
(I've seen this before)
'soft as fur' is the wordplay.
'soft' becomes 'p' (musical abbreviation for 'piano').
'fur' becomes 'sable' (sable is a kind of fur).
'p'+'as'+'sable'='PASSABLE'
(Other definitions for passable that I've seen before include "Barely adequate" , "OK" , "Good enough to be acceptable" , "okay?" , "examinations should be!" .)
