Seat foam 1991 truck

[vette]

I have 1991 cheyanne truck. I want to redo the bench seat in it. I have run into a problem with the foam. I am not sure what i need. I looks like i have just individual wires under the seat. THe most reasonable guy on foam is this.

He dosent say with or with out springs i am assuming no sag springs means one with springs and the flexwire would be just wires under the seat. I just want to be sure before i order. Thats all just feel better if i was positve. Any one have any in put or delt with this company?
