Piece of furniture, one skirted by cleaner (5)
I believe the answer is:
chair
'piece of furniture' is the definition.
(chair is a kind of piece of furniture)
'one skirted by cleaner' is the wordplay.
'one' becomes 'i' (Roman numeral).
'skirted by' indicates putting letters inside ('skirt' can mean 'circle' or 'go around').
'cleaner' becomes 'char' (charwoman is a type of cleaner).
'i' placed inside 'char' is 'CHAIR'.
(Other definitions for chair that I've seen before include "Presiding officer" , "Academic position" , "Professorship" , "Single seat" , "Top seat of committee" .)
