Relaxed – idle? Sure (8)

I believe the answer is:

leisured

I'm a little stuck... Click here to teach me more about this clue!

'relaxed idle? sure' is the definition.
I can't tell whether this defines the answer.

'relaxed idle? sure' is the wordplay.
'relaxed' is an anagram indicator.
'idle'+'sure'='idlesure'
'idlesure' anagrammed gives 'LEISURED'.

Can you help me to learn more?

(Other definitions for leisured that I've seen before include "Having plenty of free time" , "Not needing to work" , "Having much free time" , "unhurried" .)

I've seen this clue in The Guardian.
