The trampoline is great, only the structure description is somewhat complicated, you should first read both manuals (trampoline and power), because otherwise it may happen that you have to break down half the trampoline again so that the net can be mounted. A description with references to the subsequent network installation would be attached !!
We can close the zipper well, was perhaps changed?
The manager recommended this is actually not necessary, our son (3 years, 1 m tall) is also without on Tramoplin.
