Keys to resting-place (3)
I believe the answer is:
bed
'place' is the definition.
(bedding is a kind of placing)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bed that I've seen before include "In which to place the body of flowers" , "Bottom < layer" , "Bottom of the sea or river" , "Divan" , "Couch" .)
