Wise attempt to get piece of furniture (4)
I believe the answer is:
seat
'piece of furniture' is the definition.
(seat is a kind of piece of furniture)
'wise attempt to get' is the wordplay.
'to get' says the answer is hidden in the clue (I've seen 'gets' mean this).
'SEAT' can be found hidden inside 'wise attempt'.
(Other definitions for seat that I've seen before include "A manner of sitting on horse" , "Parliamentary constituency" , "Chair - bottom" , "Horizontal part of a chair" , "Chair, bench, saddle, etc" .)
