Please see photos. I believe this was purchased around 2014 and may not fit the newer strollers. Originalky for caboose and caboose lite. There is a youtube video - “Joovy Caboose Too Rear Seat Review - Baby Gizmo” that shows a similar one. Amazon link: https://www.amazon.com/Joovy-Caboose-Rear-Seat-Black/dp/B008X732O8/
