Black article scraped off back of sofa bed (6)
I believe the answer is:
bottom
'bed' is the definition.
(I know that bed can be written as bottom)
'black article scraped off back of sofa' is the wordplay.
I cannot really see how this works, but
'black' could be 'tom' (Tom is an example) and 'tom' is found in the answer.
'of' could be 'o' and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bottom that I've seen before include "MND weaver" , "Shakespeare's weaver" , "cargo vessel?" , "Lowest of the low" , "Low point" .)
