Zupapa 15ft trampoline comes in three HUGE boxes. Don't be put off, however, as the instructions are simple and it's doable: just be patient!
Everything is included in the boxes, and you won't need any extra tools. You even get a pair of gloves so that you don't get your hands dirty with oil and grease from the metal parts. They've really tried to make installation as simple as possible.
The hardest part is putting the foam sleeves on the enclosure poles. If you're having trouble like we did, just secure it with duct tape or something similar. You should be done in an hour, two hours tops, but only if you hadn't have any prior trampoline assembly experience!
