Wanting to rebuild my H2B seat this winter. The cover is actually in good shape, has one very small tear on the side that could be repaired with a patch inside. The cover is a little harder than new I'm sure, but it's ok. The base is rusty but no cracks or holes, will sandblast ok and is quite rebuildable. But the foam is bad. It has some lumps and problems, my experience has been, once you pull the cover off you find the foam is rotten and falls apart. But I don't see new H2B seat foam anywhere. So, is the H2 seat foam the same thing, same shape? The H2 seat looks to be flatter on top than the H2B. Anyone have any experience with this?

H2, H2B and H2C seats have different sizes, thus the foam is different.

I bet Bob the Seat can help. He's in England, postage might be expensive. https://www.ebay.com/usr/bobtheseat

R.B. used to get them made, but it's been a while and I don't know if he's still involved with that.

You may be able to reshape it yourself. Then you could have some gel pads inserted.

Thanks for the info. I contacted Bobtheseat, he can make the foam and the cover for any model H2 no problem.
