At sea each lounge is somewhere to relax (6,6)
I believe the answer is:
chaise longue
'somewhere to relax' is the definition.
I can't judge whether this defines the answer.
'at sea each lounge is' is the wordplay.
'at sea' is an anagram indicator.
'each'+'lounge'+'is'='eachloungeis'
'eachloungeis' with letters rearranged gives 'CHAISE-LONGUE'.
Can you help me to learn more?
(Other definitions for chaise longue that I've seen before include "Partly backed couch with one arm" , "Sofa for reclining on" , "Reclining seat with back and armrest" , "Type of sofa" .)
