Smart set resolved to get something for bed (8)
I believe the answer is:
mattress
'for bed' is the definition.
(I've seen this before)
'smart set resolved' is the wordplay.
'resolved' indicates an anagram.
'smart'+'set'='smartset'
'smartset' with letters rearranged gives 'MATTRESS'.
'to get something' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for mattress that I've seen before include "Pad to sleep on" , "Nap on this" , "Padded part of a bed" , "Large thick pad on the bed" , "Stuffed bag on which to sleep" .)
