Just like this one http://www.rei.com/product/791617?c...ferralID=ae65dd2a-5c1d-11de-a19a-000423c27407 I'm just not using our infant carrier with our Phil and Teds Sport stroller... I just put the lo in the bassinet part and 2yr old on top in the toddler seat. We did try it though with the baby in our SS1 and it does work just fine :thumbsup: I still have the original box but dh lost the directions. It was just a paper with pics of how to put it on... no words. Not sure if you could find/download them or even call a Phil and Teds dealer.... it's pretty easy though. Asking $15ppd
