Years ago my dad had an 88 Olds Toronado, one of the power seat motors stopped. So he went to a junk yard and got both front's and the rear seat out of a Riviera.
He took the power components off that he needed, then made two chairs like that out of the fronts, and a small couch out of the rear seat. They're still in my parents house to this day, very comfortable!
Probably not a lot of peoples choice of house furniture, but in my family, they fit in just fine!
I also sat wtf, not at the idea but at the seat tracks still on it. Now if you obviously have a welder and basic fab skills why would you leave those ugly tracks on there? Plus the little bit of added height will make it topple a little easier and I thought the point in wheels was so you didn't have to slide in closer to a table?
I wish I would have had the forethought for this. When I had my '84 hauled away for scrap a couple months ago it had a passenger seat in very good condition and I have a spare office chair sitting in the garage with crap upholstery.
