Stand after having arranged to get seat (6)
I believe the answer is:
settee
'seat' is the definition.
(I've seen this before)
'stand after having arranged' is the wordplay.
'stand' becomes 'tee' (I've seen this before).
'after having' is a charade indicator (letters next to each other).
'arranged' becomes 'set' ('set' can be similar in meaning to 'arranged').
'tee' after 'set' is 'SETTEE'.
'to get' acts as a link.
(Other definitions for settee that I've seen before include "two-seater?" , "Multiple seat" , "Long seat with back and arms" , "Item of furniture" , "Seat for more than one" .)
