A stand seat (5)
I believe the answer is:
stall
This clue is a double definition.
'a stand' is the first definition.
(I know that stand can be written as stall)
'seat' is the second definition.
(I've seen this before)
(Other definitions for stall that I've seen before include "Enclosure" , "Stable compartment" , "Box" , "digital protection" , "Temporise; sales booth" .)
