Seats took about 2 hours.
If you plan on doing jobs like this then I would highly recommend getting a vapor steam cleaner. Using this machine, I would have probably been able to knock that entire job down to less than 3 hours. The vapor steamer does an awesome job on nasty seats like that and does it fast. I wouldn't say it replaces the extractor in this situation but it can do a lot of things that the extractor can't.
