The assembly is ultra-fast and ultra-simple; in fact, it's my son (9 years) who opened the package and set up the tent in 2 times 3 movements, without needing any instruction. It was also too fast, because personally I wanted to see how she was bent, so be sure to be able to fold. Which brings us to the next point.
The principle is the same as Quechua tents: the painting integrates the structure that allows the tent stand: fairly rigid plastic rods to hold up, but flexible enough to be folded.
Or, if the installation is literally in seconds, we struggled a bit to fold together to make the stick in his little bag (handy for that matter). The document is absolutely not clear on this point, with tiny illegible drawings. Finally the solution we came from Youtube, thanks to user videos that filmed the manipulation. Without that, I think we would still be there ...
Note that even without completely fold the tent so that it hardly takes more space (which requires some hand), you can very easily just flatten it, and store and behind furniture, against a wall.
I would have put 5 stars if the folding instructions were clearer, or if the manufacturer had thought to include a QR code or a link to an official video to fold explanation.
