Once you fall over and roll over to get up or are forced to crawl to a wall ( all part of the fun learning curve
) you will see how a spring can get damaged. Ive seen a guy climb onto a rubbish bin and the slip ( served him right really) scraping the springs as he fell.
What you do not want is the actual spring to get a nick in it as this would be a potential weak spot. So the idea is to build up a thicker protective barrier. Ideally get an inner tube, cut it to the length of the spring. Slit it length-ways wrap around the spring and then secure in place with tape, hockey or plumbing.
