The way it's positioned is a real benefit (5)
I believe the answer is:
asset
'a real benefit' is the definition.
(an asset is something valuable or useful)
'the way it's positioned' is the wordplay.
'the way' becomes 'as' (I've seen this in other clues).
'it's positioned' becomes 'set' (I can't explain this - if you can you should give a lot more credence to this answer).
'as'+'set'='ASSET'
'is' is the link.
(Other definitions for asset that I've seen before include "blessing" , "Something useful" , "Valuable thing" , "Part of motor vehicle wheel" , "Item of value or advantage" .)
