Soft bed, perhaps for sportsman (6)
I believe the answer is:
player
'for sportsman' is the definition.
(I've seen this before)
'soft bed perhaps' is the wordplay.
'soft' becomes 'p' (musical abbreviation for piano, 'soft').
'bed perhaps' becomes 'layer' (bed is a kind of layer).
'p'+'layer'='PLAYER'
(Other definitions for player that I've seen before include "Actor - footballer?" , "Sportsman - instrumentalist" , "Sports team member" , "Performer" , "Participant in sport or game" .)
