anywhere in US to buy those cool UK carp fishing chairs?

Im needing a comfortable, lightweight fishing chair. Looking online, it seems like everything I want is only sold in the UK and shipping on a chair will double the cost. I need something comfortable and lightweight as Im recovering from back surgery. Any recommendations?

Cabelas and Gander Mountain both have similar products.
Also, Big Carp Tackle in Tulsa have them.

I use Walmart folding chairs, lightweight, foldable, and when they end up breaking, costs me a few bucks to replace. Though I don't have a clue on how you would fair after surgery...
