I was excited to get this to use with the book for 2. It's simple to install and initially seems like just what we needed. Trying it out around our family room, quickly showed that this would be returned. If you have the seats reclined on the stroller, there is no room for the 3rd child to stand. Basically can only be used if the seats are fully upright. I will be returning this. Save yourself the return shipping costs and get something else. I'm still researching a better replacement option. If I can't find an adequate rider board, unfortunately the stroller will be returned too as I need an option for 3 children.

My Toddler loves to jump on his skateboard while his newborn sister gets to ride in the seat. It's easy to flip up when I only have one child or put down when he would like to use it. Can't say enough good things about this & Peg Perego. We have the book Popup stroller that this is attached to
