Does anyone know if you can adjust the ISRI seat to be lower?
I'm talking about the air shock, the electric control is set to the lowest but it's still an inch or so too high for Cindy.
I could remove the swivel base but it looks like the bolts won't match and I'd probably have to make an adapter plate to put the seat back on.

Mine could be different since it is older but I did remove the swivel base on mine and it bolted back up with no trouble. Come over and take a look.
