Bank management furniture (9)
I believe the answer is:
sideboard
'furniture' is the definition.
(I know that sideboard is a type of furniture)
'bank management' is the wordplay.
'bank' becomes 'side' (synonyms).
'management' becomes 'board' (eg the board managing a business).
'side'+'board'='SIDEBOARD'
(Other definitions for sideboard that I've seen before include "Item of dining-room furniture" , "place for silverware?" , "Dining room furniture" , "Dior beads (anag.)" , "Piece of dining-room furniture" .)
