Is there any other carry cot that would fit on the le clerc Influencer with adapters?
You can buy the Influencer in a bundle with a carrycot, and yes, it does use adapters to be fitted onto the frame. If needed, contact leclerc customer support about options to buy the cot separately. Not sure why you would not want that one, as it is designed for the stroller and should be working better than any other one.
However... With the Maxi-Cosi adpaters that leclerc offers, you should be able to attach GB's Cot To Go in theory, but I never tried in person so cannot say how the center of gravity will be with that one. So, there is this extra option, however I would not go for it unless truly nothing else works for me. And you can always use a reclining car seat (Joie i-Level for ex.) on the car seat adapters instead of a bassinet.
