Live at the back of beyond, somewhere comfortable (3)

I believe the answer is:
bed
'somewhere comfortable' is the definition.
I can't judge whether this defines the answer.
'live at the back of beyond' is the wordplay.
'live' becomes 'be' (synonyms).
'at the back of' indicates one should take the final letters (I've seen 'at the back' mean this).
The last letter of 'beyond' is 'd'.
'be'+'d'='BED'
Can you help me to learn more?
(Other definitions for bed that I've seen before include "Place for patient in hospital" , "pit" , "For sleep and flowers" , "Matrimonial duties" , "Divan" .)
