The seat is in really good condition for the most part, there is one tiny rip you can see in the second pic, third rectangle back on the near side. It's also missing the strap. I've got a K2, with 2 hinges on it (instead of the one on this seat), and I don't really think I can get this sucker to fit on there. Again, I'm not an expert
If I can't use it, I'd probably be looking to sell it, as I'd have no use for it.
