Trampoline pads

I am looking into getting into in home childcare and have recieved the pack that tells you about the reqirements your house has to meet etc. one of them is that if you have a trampoline it must have the pads on them however they are really really exspeince to get made and cannot find anywhere that sells them. if anyone has an old tramp that they dont use and wouldnt miss the pads id be happy to pay something for them..

im not sure what my tramp measures but if theres anyone that has any, ill go measure, cheers
