I’m 6’2” and had back surgery. In stating this, the Pat’s seat is very comfortable for me, but have to tweak it a bit after my wife uses it. Pardon the pun, but the tweaking is pretty much down “pat” now. My setting is first drop the seat to the lowest setting, then back up two pumps, move the back rest up slightly, then move the seat up about 3 inches.
I’m sure you’ll find a setting or two which works for you.
