The answer is YES and NO!
In fact, when you unpack your new YOYO bassinet, it will be in kit form, and so will need to be fully assembled.
This means that the bassinet can be completely dismantled to save space.
For example, to fit the YOYO bassinet in your car.
Strictly speaking, however, the bassinet is not foldable.
If you take it apart a little, you can fold the bassinet as shown in the photo above and in the video.
By dismantling the bassinet, you can fit the two parts together.
It’s not like the Stroller 6+ pack that folds completely.
Personally, in 3 years, I’ve never had to take it apart completely, or even fold it.
Even when flying with the YOYO bassinet.
