These are great chairs,very well made and still available new, but because they were so popular are available very cheaply secondhand.
The years haven't been kind to my chairs, though, and the webbing started to break to the point where I couldn't use them anymore.
At the same time, bike innertubes have become incredibly cheap. I love my cycling, but I find it abhorrent that my fellow cyclists seem to think that because this is the case, it's acceptable to leave punctured tubes at the side of the road.
This was the germ of an idea....
EDIT: If you're looking to replace the cane on a cane chair, I have just found:
So all credit to TimAnderson for a nice instructable.
Step 1: The Chair
Step 2: Cut the Tubes
Where to find these? Bike shops don't repair punctures anymore, so you might be able to get some from the bins. Mind you, I regularly find these abandoned at the sides of the road by lazy, thoughtless roadies.
These ones had woods valves, so no use to man nor beast.
Step 3: Thread the Tubes Into the Chair (fiddly)
Step 4: Tying Off (really Fiddly)
Step 5: All Done!
The tubes won't last as long as the original webbing, but they are easy and cheap enough to replace.
(excuse the mess, I'm moving!)
