Question: How many springs does it have?
Document: We bought this trampoline for Christmas 2012. It still looks fairly new. Unfortunately, the kids interest in it declined faster than I'd hoped. They still get excited about it if they have company. I guess it's just not as much fun unless too many people are jumping and there's a real risk of a serious head injury. Ours is situated on a narrow bit of flat land next to a steep incline.
Answer: no
