Place support for item of furniture (6)
I believe the answer is:
settee
'item of furniture' is the definition.
(I've seen this before)
'place support' is the wordplay.
'place' becomes 'set' ('set' can be a synonym of 'place'**).
'support' becomes 'tee' (tee is a kind of support).
'set'+'tee'='SETTEE'
'for' is the link.
(Other definitions for settee that I've seen before include "Small sofa" , "Comfy seat" , "Long indoor seat" , "Item of furniture" , "Seat for more than one" .)
