Pay to get comfortable (6)
I believe the answer is:
settle
I believe this is a double definition.
'pay' is the first definition.
(as in settling a bill)
'get comfortable' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for settle that I've seen before include "Reach an agreement or become calm" , "Decide - colonise" , "Come to rest; bench" , "Comes to an arrangement with the bench?" , "Colonise with a seat" .)
