I was thinking the same. I upgraded from the old leather version to the Foam Heel seat. Now I am thinking about the Carbonium one. I sat on one in a shop last week and it feels like it will last, unlike my old leather version which the foam inside gradually got softer and softer until I felt like there was no cushioning/padding between the leather exterior and the plyboard it’s stapled to.

The carbonium has a gel inside I think along with denser foam? It’s hardish but softer than the foam heel seat. The Club version has a softer leather exterior but the leather feels like it could rip/tear around the pole support loop after a bit of use.

Hope you don`t mind me jumping on this thread but I read DH`s reply about the leather seat and the foam flattening. I have a leather seat on mine and recently when I`ve been sitting on it for a while my left bum cheek starts to hurt and I get a pain down my left leg. Do you think that its the foam flattening and sitting almost on a piece of ply for 5 or more hours that causes this problem? Again sorry for jumping onto this thread.

I had the same experience, although mine was caused by sciatica 🙁 Pure agony sitting for even half an hour but the bites kept my mind off the pain.

My leather seat was off a 2003 Rive RX so it’s age was probably a factor for the interior foam giving up, or else they made them softer on the older models.

Buy yourself a second hand milo gell cushion send it to Matt (kinsway allstart)on this site and he will make it fit,it will be the best seat you can get for your box.
