Why is there no factory seats available

Simple question. I’m restoring a 2002 Chevy S10 V6. I have been looking everywhere for a very simple part…..a seat. Just a simple seat. Guess what!? You have three choices. One of those stupid ridiculous high back racing seats (must be for handling all 100 horse power), used, nasty seats from eBay, or seat covers to go over the completely broken seat you have. I’m wondering why new replica factory seats don’t exist. I don’t want a Cavalier seat or a Sunfire seat. I don’t want a Blazer or Bravado seat. I simply would like an aftermarket plug and play effing S10 seat. Thanks for any help lol
