Lounger rising late securing cushy job at last (3,3)
I believe the answer is:
day bed
'lounger' is the definition.
(type of furniture item)
'rising late securing cushy job at last' is the wordplay.
'rising' says the letters should be written in reverse (going up in a down clue).
'late' becomes 'dead' (similar in meaning).
'securing' indicates putting letters inside.
'at last' indicates one should take the final letters.
The final letters of 'cushy job' are 'yb'.
'dead' back-to-front is 'daed'.
'daed' placed around 'yb' is 'DAY-BED'.
(Other definitions for day bed that I've seen before include "Hospital berth for short stay" , "Kind of couch or sofa" , "Kind of couch or 1 dn" .)
