[PAX5]

I've owned all three. IMO:

First pic - Sport seat:
- hard and unforgiving seat bottom after 2 hours in the saddle
- side bolster too high ... will cause your voice to change after a few ingress and egress.

Second pic - Comfort seat:
- 20 way adjustable .. the ultimate in comfort

Third pic - Standard seat:
- actually feels better than the sport seat, because the bottom seat cushion is firm yet not hard, for long haul driving.
