Item of furniture with unusual charm to put on display (8)
I believe the answer is:
armchair
'item of furniture' is the definition.
(I know that Armchair is a item of furniture)
'unusual charm to put on display' is the wordplay.
'unusual' indicates an anagram.
'to put on' indicates putting letters inside (some letters put on or wear others).
'display' becomes 'air' (air can mean to display or show something).
'charm' is an anagram of 'rmcha'.
'rmcha' inserted into 'air' is 'ARMCHAIR'.
'with' is the link.
(Other definitions for armchair that I've seen before include "Comfortable seat with raised sides" , "Sort of detective" , "Piece of furniture" , "Place for critic" , "TV viewer's seat" .)
