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

'parlour' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for lounge that I've seen before include "Living room" , "Recline lazily; room" , "Relax in sitting room?" , "Loll - sitting room" , "Comfortable room - relax in it" .)

I've seen this clue in The Mirror.
