Somewhere to sleep in Matlock? (8)
I believe the answer is:
mattress
'matlock?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I can't see?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for mattress that I've seen before include "For the smart set to lie on?" , "Sleeping support" , "Stuffed bag on which to sleep" , "Large thick pad on the bed" , "Padded bag on which to sleep" .)
