Furniture employed off stage (7)
I believe the answer is:
dresser
I believe this is a double definition.
'furniture' is the first definition.
(I know that dresser is a type of furniture)
'employed off stage' is the second definition.
(I've seen this before)
(Other definitions for dresser that I've seen before include "Item of furniture - actor's assistant" , "helps actor get ready" , "one employed backstage" , "Piece of kitchen furniture" , "Item of furniture with shelves and drawers" .)
