The new trampoline is springier than the old one.
Springier → It is formed from "spring" (from Old English *springan*, meaning to leap or jump) and the suffix "-ier" (indicating a comparative form). The word "springier" means more springy or having more ability to leap or bounce.
Think of something that can 'leap' or 'jump' ('spring') and remember that 'springier' means it can do so more than something else.
