Mountain Buggys are a big investment, but well worth it. The Double Terrain is for those serious about getting off-road, but great in town too. The fixed front wheels provide accurate steering especially when off-road, no need for constant steering. The low centre of balance means it's surprisingly manoeuvrable. Seat positions are independent of each other. Weighs 14kg Width 74cm Length (when folded) 110cm Suitable from birth to 4 years (maximum weight 25kg per seat).
