The seats in my ’89 IROC are kind of worn and I am looking for a cheap seat cover set for front and back seats till I can afford to recover them, any ideas?

 

Fronts are easy enough - their abundant at any auto parts store, or walmart.

Rears are different. Since the rears are cup shaped, there is no way of doing covers for them without sewing something together to fit in the cup - any other way you try and cover them they end up like a tupperware bowl with a lid on it.

Easiest way is to get some nice 4th gen seats from the boneyard, and swap the entire seat set in, both fronts and rears - then you get nice seats. I got mine from a private seller, think I gave $80 for the whole set (frt & rear).
