Hello - just about to try our 10 week old DD in our Baby Jogger. To date, she's been on top in a Maxi-Cosi, which has worked brilliantly.
The seat surface on its own looks a bit hard - if you've got one, have you found that to be the case? And if so, what have you used to soften it up / line it? eg, have you gone for the Baby Jogger foot muff, or something different?
Cheers!
