I'm 5'10" and 30-32 inseam, 230 lbs. LOVE this seat.
Got it 2 days before Christmas. I've gone a little over 350 miles on it and my sweetie has been with me for about 150 mile. That's not bad mileage for up here in Ct in December, January and February. Anyway it was cold weather but that seat was everything I had expected and my sweetie is very happy with the comfort. The rider backrest is very nice when I'm alone and I remove it when sweetie comes along. She snuggles up close and doesn't usually sit where passengers are supposed to, (all the way back against the backrest).
