That's probably actually the correct word and not a typo/ocr error.
The entry in the
Trésor de la langue française informatisé via
Wiktionary gives a secondary definition of what amounts to a bouquet-like decoration assembled from feathers.
So if he has to move some kind of interior design or hat decoration ornament out of the way before he can sit, that would explain it.
ETA: oops, there's actually a 3rd definition which amounts to a duvet (the actual definition roughly translates to “eiderdown, feather coverlet”, and quotes an example sentence of “pillows behind the back, a coverlet over the feet, his/her balaclava on the head”) and that's probably it.
