Room right for a comfortable chair (7)
I believe the answer is:
lounger
'a comfortable chair' is the definition.
(I've seen this before)
'room right' is the wordplay.
I cannot really understand how this works, but
'room' could be 'lounge' (lounge is a kind of room) and 'lounge' is found within the answer.
'right' could be 'r' (common abbreviation) and 'r' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for lounger that I've seen before include "Extending chair" , "Comfortable outdoor chair" , "Casual coat" , "Relax on this" , "Sunbed" .)
