might need to change the spring rate since you stiffened up the chassis.
seats are measured by fart count, not mileage
 
probably should have just used a sheet of plywood. That rebar is gonna wear your ass out.
 
When rebuilding 240 seats or servicing the seat heater element, I install a layer of cardboard between the foam and the seat grid. This protect the wires and springs from digging in and cutting the foam apart as well as helps keep the plastic reinforcement cast into the seat foam somewhat intact. USPS medium flat rate boxes are what I tend to use. Have also heard about people using fiberboard (aka a old clipboard) in this manner.

Will next day air boxes work as well?
 
I used the wagonmeister support grid last time I rebuilt a seat about 8 years ago. As I recall it was mostly a piece of sheet stainless which was a good firm base for the seat.
