It's got a quick release, and appears to be pretty level given the age of the saddle, and spring suspension being old and somewhat worn out, the reason I say It NEEDS to be replaced fairly soon (in addition to the discomfort) is that the padding is split in two places, and whatever the "stuff" (some kind of synthetic foam) is, is visible. I've got the height set the way my Dad taught me...so that astride the saddle my toes can touch the ground enough to balance at a stop, so I get maximum push on the downstroke.
And COOL would be SOOOO Welcome here...on the upside, it's a great way for me to lose the water weight I gain this time of the month! LOL The downside, even for a short (like 15 minute) ride to the store, I have to carry at least 2 water bottles, but hey, it beats heatstroke! LOL
