This is the instruction manual for the double snap n go. The last page shows several carseats that are compatible. The instructions for the single doesn't include the list, but I would assume it would be the same. I had the double snap n go and I used baby trend carseats because I knew there was no doubt those would work. If you have a specific carseat already you can call baby trend and ask them if it is compatible.
