Replacing Torn Leather Seats

I just bought a 1994 Explorer as a second car. It is a nice driving vehicle but the driver seat is shot. I was wondering if anyone has experience swapping seats out. I have found a couple sites that have used seats for sale that would be much better than what I have and likely cheaper than having mine recovered:

This is one example. I was curious if anyone has experience if they could try to articulate some of the basics when investigating this. Thanks.
