What's cool about this seat is that all positioning adjustments can be done while the user is seated, This makes adjustments easier on everyone.
I've had my seat a few years and it works great. I added velcro to the underside to keep it from sliding. It is a bit pricey at around $400 but it's well worth it. Most insurance covers it.
