I believe the answer is:

feather ones nest

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

'get comfortable' is the definition.
I can't tell whether this definition defines the answer.

'tennessee tho' far off' is the wordplay.
'off' is an anagram indicator.
'tennessee'+'tho'+'far'='tennesseethofar'
'tennesseethofar' is an anagram of 'FEATHER ONES NEST'.

'in' is the link.

Can you help me to learn more?
