Who are are the main manufacturers of airliner seats ?

Do Boeing / Airbus and other airliner manufacturers design and make their
own or are they supplied under contract by companies that specialise in the
manufacture of seats ?

I doubt that more than 25-30% of an airliner is done in house, starting
from engine to fuel tanks, to avionics and servocontrols, landing gear
and so on they all comes form vendors. Nowadays the two bigs are trying
to have vendors sharing the risk (it means developing at own risk, and
getting payed only when the aircraft is sold).

Seats are part of the items coming from vendors off sure.
