Small article of furniture, durable (6)
I believe the answer is:
stable
'durable' is the definition.
(thesaurus)
'small article of furniture' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'article of furniture' becomes 'table' (table is a kind of article of furniture).
's'+'table'='STABLE'
(Other definitions for stable that I've seen before include "Sure!" , "Sound" , "It might accommodate Arab" , "Fixed; stud building" , "Home for horses" .)
