Swap seats form 2007 fit to 2015 fit
 

I have a 2007 fit with 200,000 plus miles. It has the most comfortable seat in a car that I have ever driven in . I just purchased a 2015 Fit EX. I find the seat most uncomfortable, however I love everything else about the car. If I swap the 2007 seat into the 2015 will it fit. Will there be issues with airbags? If I do this swap than the car will be perfect. Thanks for the help and advice

You can always try and see... seats are usually bolted down with 4 bolts, 2 in front, 2 in back, hidden under plastic trim, and there's usually an electrical plug you need to disconnect under the seat. You could put new and old seats side-to side and measure each to see if the bolts are about the same configuration, then drop a seat in and see if it works. My hunch is any electrical harness plugs will be different, and would require customization, specifically around any side air bags built into the seat.
