97 Seats

Just bought a 97 blazer 4 door. The drivers seat seems soft so I looked underneath and found thate wires/springs hanging down on the floor. Is the non power seat hard to remove. Can the support wiring be replaced? also wowuld like to add some padding and lumbar support. Can I use seats from another year?? I am just noticing how cheap the interiors are on these trucks. lots of plastic squeaks and rattles inside.
