A spring trampoline is a type of trampoline that uses metal springs to provide bounce. A springless trampoline, also known as a rebounder, uses bungee cords or stretch bands instead of springs to provide bounce. Both types of trampolines have their pros and cons, so it really depends on what you are looking for in a trampoline when deciding which one is better.
Spring Trampolines:
-Pros: Springier bounce, more durable than stretch band models
-Cons: Can be more expensive, require more maintenance (tightening/replacing springs)
Stretch Band/Springless Trampolines:
-Pros: Cheaper than spring models, don't require as much maintenance
