Rehash old upholstery's stuffing to make bolster (4,2)
I believe the answer is:
hold up
'bolster' is the definition.
(I know that bolster is a kind of hold up)
'rehash old upholstery's stuffing' is the wordplay.
'stuffing' indicates a hidden word.
'HOLD-UP' is hidden within 'rehash old upholstery'.
'to make' acts as a link.
(Other definitions for hold up that I've seen before include "robbery" , "jam" , "Exhibit" , "lift" , "Hitch" .)
