Low upholstered seat (7)
I believe the answer is:
ottoman
'low upholstered seat' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ottoman that I've seen before include "Turkish (hist.)" , "Upholstered footstool" , "Shared seat" , "Backless seat" , "Am not to (anag)" .)
