Can you fold up an urban jungle buggy with the stalk seat still attached to the standing platform?

Hi Rachel, yes I believe it is compatible with the Buggyboard Maxi+. When it comes to folding, we would recommend unclipping the Buggyboard first. If you are unsure though, feel free to test it at your local Baby On The Move first. Here is a list of our store locations here:https://www.babyonthemove.co.nz/store-locations/. Hope that helps
