these work in a different manner.. the pool noodle fix fixes breaks in the square springs whereas this "noodle" restores the front springs and brings it back up to the proper height..

the black noodles are also of closed cell construction and will not degrade as fast as pool noodles which are open cell construction... I have seen a set go on ebay for $25.. but I think a set on ebay is 4 pieces.. I'll look into it later
