Fairly easy to put together but you need 2 people. The worst part is looping the net onto the trampoline itself, it's just tedious but not a huge deal. Took about 2 hours with 2 people. My kids are 11 and 8 and they love being on it together. It's not really large enough to have more than 3 kids jumping on it without smashing into each other, but that's probably part of the fun!
