Fat Cat LCS

I bought this new from a friend, unused. It did not come with the adapter for the pump, which was a big nuisance. Who has these adapters? Neither of our local sporting goods stores carries them. I had to wrap black tape around the end of my pump and force-fit it in the valve.

I love this tube, durable, well made and stable. I do have an issue though.... the back rest is flimsy and does not come up on the back very high; can't lean back against it very well when start to get tired or if paddling against the wind, position of comfort is leaning forward. A friend has the same tube and the same issue, he used the hard plastic back from a folding chair inserted behind the seat to support the back rest, I may do the same.
