Male in favour of lying in bed for ease (7)
I believe the answer is:
comfort
'ease' is the definition.
('comfort' can be a synonym of 'ease')
'male in favour of lying in bed' is the wordplay.
'male' becomes 'm' (common abbreviation).
'in favour of' becomes 'for' (I've seen this before).
'lying in' means one lot of letters goes inside another.
'bed' becomes 'cot' (cot is a kind of bed).
'm'+'for'='mfor'
'mfor' placed within 'cot' is 'COMFORT'.
'for' is the link.
(Other definitions for comfort that I've seen before include "Give relief from pain or grief" , "Relief; soothe" , "Consolation" , "Console, offer solace" , "Soothe - console" .)
