Outdoor Chairs

So the elements and the squirrels have done a real number on my outdoor chairs, and I have not been able to find any pads to replace them with

So I deceided to cover the ones I had even tho they are in bad shape. So now what to use to cover them that won't cost a fortune?

The one on the left a fabric shower curtain I recently replaced that was still in excellect condition and the one on the right is a $3 drape from Tuesday Morning! Not bad!
