I had items shipped recently that arrived with long foam pads as packaging material. I am not sure what exactly it's made from. The pieces are about one inch thick, 2 feet long and 10 inches wide and very cushiony. They'd work great as a garden kneeler.  I have about 15 pieces like this, they are clean and new.  Please contact me if you'd like to pick one up on my front porch.

Thanks, Laura
