Piece of furniture sent east (4)
I believe the answer is:
seat
'piece of furniture' is the definition.
(seat is a kind of piece of furniture)
'sent east' is the wordplay.
'sent' is an anagram indicator (send can mean to excite or stimulate).
'east' is an anagram of 'SEAT'.
(Other definitions for seat that I've seen before include "Position (in parliament)" , "Somewhere to sit" , "Box ---, position of advantage" , "MP's place in parliament" , "Constituency; location" .)
