Can I make an airseat from this seat? Its on a 24" Sun.
Yes, you can, and I have done it (for a friend). I think I used a folded-in-half 16" tube held in place with black duct tape strips. Don’t wrap the duct tape all the way around the seat or you’ll lose any hand holds. Experiment with folding the tube, and when you find a good way to make it fit, drill a 1/4" hole for the valve stem. You may need to try more than one size of tube to find the right amount of volume for you. After you have it taped in place to your liking, you may make a cover of some sort, or not(I didn’t).
