Time to put keys under couch (3,3)
I believe the answer is:
day bed
'couch' is the definition.
(day bed is a kind of couch)
'time to put keys under' is the wordplay.
I cannot quite understand how this works, but
'time' could be 'day' (day is a kind of time) and 'day' is located in the answer.
'put' could be 'bed' (bedding is a kind of putting) and 'bed' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for day bed that I've seen before include "Kind of couch or 1 dn" , "Hospital berth for short stay" , "Kind of couch or sofa" .)
