Sports equipment is annoying. It's disturbing downstairs, so I'm still bothering to ask you to go. This kind of sports equipment is not allowed.
As long as you take protective measures, such as putting silicone pads under the four feet of the collision bed, you can reduce the noise of the collision bed when it slides.
Even if you let your child jump and play on the trampoline, he won't make a lot of noise. After all, he doesn't touch the floor directly.
