Hi everyone!

By no means are my seats in bad shape but given the age of my car there are just some creases and marks and the bottom is not es firm as it used to be.

How much would new seats be? Has anyone tried to get them re-done? If so what are the options? Is there a kit? Do I go to a upholstery place?
If I bought a kit, do they work well and is it difficult to do? What can be done and what can't be done?

I'm open to any advise from y'all.

Nick
