OK, thats it I've had enough of numbing that part of my anatomy so have decided to an airseat conversion on my viscount seat. I've already removed the cover and am now looking at the seat wondering how much foam to remove from it. I understand that its a good idea to leave a good part of the front and back in place but wasn't sure how far down the sides I need to cut away. I was wondering what size tube is best as I have a 16x1.75 which I thought might do. I'd be most grateful for any hints on this and also if anyone knows of any links with pictures of the procedure.
i've done this before but with the help of an upholsterer.
i got a 12.5" tube but it was too small so i would advise a 14" i think ure tube would be too big.
i got some new material for it as well (denim). i didnt remove any of the old foam but i don't really know if i should have or not, it seemed to work ok. i folded the tube in the same way as described for a miyata conversion (search for something about that). i drilled a hole through the foam at the back and through the base just in fron of the rear bumper.
i then got some foam off my mate and cut it into 2 triangles for where the inertube wasnt( u will understand when u find how it's folded). then my friend re-upholstered the seat for me with denim😄.
