I did really like the iCandy but was just put off iCandy after all the problems I had with both the Apple and my old Cherry! Also trying to store all the bits of the Pear was a nightmare! I love how this one folds with both seats on and for a big pushchair, it folds really compact.
Genies no I don't think she will be in it long either. She's very tall and her legs hang right over the edge. That's the only complaint I have so far is no foot rest. But she was the same in the Graco and that did have a footrest, but she still dangled her feet over the edge as her legs are too long! In a few months I'll prob take the bottom seat off and put a buggy board on for Holly instead, then Evie can go in the main seat facing me. By that time she will be sitting up a bit too. Those who have used buggy boards, what age did you use them from? I don't think Holly would use one yet, she'd just try and get off all the time, plus she still likes to nap whilst we are out, although this is becoming less frequent.
You can use it as a single, you just take the bottom seat off. The main seat can be forward facing or parent facing, but in reality you can only have it forward facing with the second seat on otherwise there isn't much room. Apparently they do sell extenders to make the main seat further forward though so it might work with those on. You can also use a Britax car seat in place of either seat, but you need special adapters for the lower seat. I've just bought the soft carrycot to go in the lower seat for Evie so she'll be a bit more comfy whilst she is little, although she did seem perfectly comfy in it today and slept the whole time, so she can't have been uncomfortable!
