Piece of furniture in church being collected by member, look (8)
I believe the answer is:
armchair
'piece of furniture' is the definition.
(armchair is a kind of piece of furniture)
'church being collected by member look' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'being collected by' says to put letters next to each other (I've seen this in other clues).
'member' becomes 'arm' (arm is a kind of member).
'look' becomes 'air' (I've seen this before).
'ch' put after 'arm' is 'armch'.
'armch'+'air'='ARMCHAIR'
'in' acts as a link.
(Other definitions for armchair that I've seen before include "Place for critic" , "Roomy seat" , "Furniture item" , "Lacking practical expertise" , "Amateur" .)
