It took about an hour to install the seats for both the driver and passenger. Tried first to take out the front bolts, but the bolt closest to the center was much harder to try to line up correctly. Ended up loosing the rear bolts of the seat to adjust the seat. That was a pain. These bolts are in excellent condition, but using a socket set takes a bit of time to loosen them. The passenger seat was much easier when I knew what I needed to do. How would they feel compared to the standard chair? Honestly, it is quite a bit more comfortable. It took a bit to get the seat in the correct position, but my legs definitely had more room with it jacked up on that angle. Glad I purchased these,
