We have the W4 Elite and the W4 attachment fits perfect! And is compatible with our Graco Snugride Snugfit LX infant carseat that came with our Graco Modes nest2grow travel system. Not sure why someone else reviewed that the W4 piece it isn’t compatible with the elite because it 100% is. Great addition, was an easy install but have a screwdriver handy to initially put everything together and then once it’s all put together the base itself that rotates can easily be removed and put back on.

This is a nice adapter for the portable wagon. It helps carry newborn twins. The only problem is that the total machine is a bit heavy for a small mother.

This adapter not only was super easy to attach but it still allows for room under the car seat to place items. We typically only have one child on the seats next to it but there is still enough room for two kids in the front seats. Bought this adapter instead of doing a double stroller because our kids have always outgrown everything so quickly so this is just a temporary thing until he can sit up and ride inside the wagon. We bought this to fit our Maxi Cosi car seat. I believe they have just released more models for different car seats. Well worth it for our family!

This isn't compatible with the W4 elite pro. It fits on the wagon but you're unable to fold the wagon with the attachment. You would have to remove the brackets from the wagon to fold it.

Love this car seat adapter! It is super easy to install and allows you to rotate 360 so the car seat can face different directions depending on where the sun is. It leaves enough space for kids to sit comfortably in the bench seat. Highly recommend if you already have a wagon and don’t want to waste money on a stroller.

If you own one of these wagons, you're going to want to get this attachment! This attachment fits different types of cars seats (I've used 3 different ones with it). It's sturdy, mobile, and gives you a perfect view of your infant while your toddlers sit in the seat section of the stroller, or if you're hauling your stuff around. The only reason I gave 4 stars instead of 5 is because I had to glance at the instructions ;) This is really easy to set up and adjust.
