Necessary accessory if you have a second child!!! Quite sturdy, easily and quickly adjusts to the stroller...if you don't use it, it folds and doesn't bother at all...it's easy to handle the stroller and the child really enjoys it!! HIGHLY RECOMMENDED without a second thought!

Very good application on the book 51S stroller. Easy to drive, easy to climb sidewalks just like a stroller without the footrest. My older son (4.5) enjoys the rides comfortably and I have him under control while moving around the city.

Just what a parent needs when they have both children together for a walk.. Our 3-year-old loved it, and so did we! It follows the stroller nicely on smooth surfaces. We lower the child when we encounter small obstacles and stairs.. It easily attaches on top when not in use. And the siblings keep each other company without any complaints or anything! Haha

First day today that we are using it!!
Very good!!!! Our 2-year-old enjoys it very much and doesn't want to get off!!!!! It solved my hands, especially when I am alone with the 2 babies, without any other help!!

It solved our hands. Now both little ones can go out for a walk without whining or mishaps. Good quality and smooth rolling.

Very useful accessory. We can cover longer distances with the stroller, with the older child (2 and a half years old) on the platform, without getting easily tired and asking to be carried. It even seems to enjoy it. In terms of construction quality, it is excellent. The rest of the stroller follows without problems when going up and down the sidewalks when the child is not stepping on it (I did not attempt to try it with the child on top). Of course, when the child is on the platform, the bag with the essentials goes in the space under the stroller, they don't fit together. Luckily, the Book has enough space down there. Overall, it is a purchase that we are very satisfied with and that's why I recommend it to everyone who has an older child but only one stroller.

Very good and high quality. It is convenient because it locks in a vertical position, making it more convenient without the child on top. It also has hand rests.
