When I got my bus all it had was a high bench seat at the back, (apart
from the front ones of course)  as it was originally an 11 seater. I got
a proper rear seat and a middle seat but my eldest daughter complained
that she found the middle seat blocked her view. So I got a pair of rear
facing jumpseats. However the jumpseats are still resting on the surplus
middle seat in the back of my shed as I've not got around to installing
them yet!
I've also got a hole in the wooden floor for the midlle seat rails.

However if I need extra seating it will be quicker to put the middle
seats back until I do install the jumpseats. Even then, you never know,
I might need the the middle seats.

Of course none of the seats match so I shall have to get them all
recovered sometime.

(And the front seats are from a Volvo.)
