I have the emmaljunga single cerox, with the reversible handle, and I love it.

It fits in the boot of my corolla seca, but it is big, and I have been verbally abused by mums (I'm not joking) because my pram is too big and gets in their way in parents rooms!

I have seriously considered getting a smaller one for quick trips, or if I know it would be a tight squeeze at the place I was going to.
