Vase included in furnishings (3)
I believe the answer is:
urn
'vase' is the definition.
(urn is a kind of vase)
'included in furnishings' is the wordplay.
'included in' indicates the answer is hidden within the clue.
'URN' is hidden in the letters of 'furnishings'.
(Other definitions for urn that I've seen before include "Ornamental vessel" , "Spore-producing capsule of a moss" , "Ashes trophy" , "Tea vessel or ash container" , "Large pot for coffee or tea" .)
