I rode one, you just provide a screwdriver (surprisingly) but the final assembly is fairly simple and the installation in the car is very convenient. I bought during sales which made it even better price / quality and I do not regret. Practical, aesthetic, the cup holder are a little extra nice. My son found it very comfortable, it looks really attractive.
One downside: a belt guide provided, we say that it is great so that in the end it takes time to understand how to install it because the description does not really explain how to use it - but that's a detail.
