does anyone have this?

does anyone have this on their uni? also would it work with a KH fusion saddle?

Yes it will fit a KH saddle:)

just buy a 12 inch inner tube, it does the same thing, almost everyone does it for air saddles and its not unneccesarilly expensive

i know i would rather spend 3 bucks instead of 17 on almost the same thing

That’s a cover for the tube. You still need the tube.

I think the tube comes with it

Yeah and it SUCKS! Terrible design and TOO BIG! Flops and squishes all over the place. So I cut it in half, got A 12" TUBE , cut off the flapand closed both ends with velcro. taped it securely to the seat base and put a soft foam (saddle shaped) pad on top of the air pillow and it’s the BEST air seat ever! But the fold-over SUCKS! Plus, after you cut it in half, you now have TWO air pillows!
