Dear All
As another idea -
I modelled a seat by laying 4 plies of bid over a cheap plastic chair
with good back support as used in public buildings.
To support the back I cut a pair of slots on the bend between seat and
back to accept a supporting strap from the seat belt attachment bolt -
this also allows adjustment for tilting the seat.
The front of seat is supported by 2 sprung shoot bolts which latch
sideways into an array of holes in a diamond shaped piece of 3/8 ply,
and attached at each side of the front edge of the "seat".
I have not yet sat in it for hours to try it!

Have folk built out the seat back to follow the line given by the
headrest forward face? This would seem more comfortable and also
lower my head by being somewhat more recumbant.
Hi Paul,
I did exactly that, although my cushions are of my own design (and
expertly sewn by my lovely bride)
What I did was continue the line of the headrest down to the seat pan
to get an idea of the size and shape that the seat back cushion would
need to be. Then, I took some blue foam and hot knifed a wedge of sorts
that has a curve on the front lower side. This wedge sits in behind the
cushion foam and fills the void left by the change in angle of the seat
back. The blue foam doesn't allow the cushion foam to crush into the
void and as such provides excellent lumbar support. It took several
attempts to get the right lumbar support, but I finally arrived at a
shape that makes the seat comfortable for hours. I designed the cushion
covers to hold the foam wedge and the foam padding in place. I can send
you some pictures and or a drawing of the hot knife template if you
want. It might not fit your back as well as it does mine, but it would
be a good place to start.
Anyway, hope it helps!
