The stuff used to cover middle grade office chairs - the ones with
arms and lever adjustments - has resisted the efforts of Millie and a
couple of her friends for over six years now.  It shows wear, and some
snags, but all in all, both my chairs are in remarkably good shape for
their ages and the number of cats abusing them.

PVC with slitely rough finishh.

Or watever you want but have a looose cusion over it so they cant grip
it to scratch. Match the color to there fur.

I wonder if there is any way to produce or find someone who is already using
a fine curtain of metal links, like jewelry ... small and light but made of
steel or something similar. It would look nice and be comfortable but I
guess very expensive to produce unless someone already has something
similar.
