I can add another use for the pipe insulation too. My computer chair is the type that has the full metal arms that form a '0' shape on its side and are attached to the base frame on one side and the back frame on another. On the top edge are padded arm rests but the front faces are the bare metal tubes. Back in March I bought a beautiful new acoustic bass guitar as a birthday present to myself and I lived in fear of scratching up the exquisite quilted maple finish on the tubes. I fitted a couple of lengths of the pipe insulation on the bare metal sections of the chair and no more worries! I can now play the bass in the chair without fear of getting the back of the guitar all scraped up.
