The Mountain Buggy has a bassinette attachment and can also be taken on rough terrain. I didn't get the bassinette as it was an extra $250 on top of the pram and only lasts for a few months as it is generally used for a newborn. I however just used the 'normal' part of the pram for DD for when she was newborn and still using it! I love it to jog with (not now with fat tummy though) and my sister tooking it trekking (not my pram but her MB) in New Zealand.
