Further to my recent description of a cheap and quick air cushion made from a cycle inner tube, some insulating tape and three socks:
For the first half mile or so it was absolute luxury. Perfect. Just a little bit harder to mount. After about 5 miles I removed it and the rest of the ride was much better! I found that if I put enough air in to give any real padding, it became too bouncy. The uni felt more ‘remote’ and I had less control. It hurt in different places. I am becoming convinced that a handle, and regular breaks, are the way to go.
make a dogbone air pad and put it under a roach cover,works good.

I got the same effect the first time I made an air seat.
Like a bouncy castle it was. I had to left a lot of the air out.
Still, a little air is much better than no air, in my experience.
I have twice punctured the tube and really noticed the
difference (no idea how but I assume it is related to being
smarter^H^H^H^H^H^H^Hlarger than the average bear).
I had the same problem with my first air seats. It felt like I was sitting on a 1970’s era waterbed.
To fix that problem I put my tube (a 16" tube) in a single layer air pillow that I sewed myself. Then I put a foam cushion on top of that (I use the foam from a Miyata seat). The combination of the foam and pillow case dampens the bounce from the tube so I get a lot of cush but very little bounce. No more of that ‘remote’ feeling, and no problems using the hips to control the uni. It makes for a thick air seat and requires the use of a Roach seat cover. There is still room for improvement, but I like it.

This made me wonder. Has anyone tried other fluids than air in their
“air seat”? E.g. water, or oil? If dampening is a good thing, a more
viscous fluid, especially if it would be combined with a porous
material inside such as those self-inflating camping mats could work
wonders.
