I've previously used the ikea cable tidies as already posted but currently use a hose pipe I cut a slit in with a pen knife, I then covered in parcel tape for more protection. It depends how flexible you need it to be, the hosepipe is less so but I think I feels more secure. I always felt the cable tidies just gave me time to jump off my chair and stop the bunny chewing rather than the protection of the horepipe in which I can leave then un-attended.
