Dh and I have started looking at prams and like the look of the mamas & papas Ultima 3 in 1 combination. Have had a look at the different chassis and thinking about the x-cel chassis rather than the MPX one. I don't drive so would spend a lot of time walking and, on and off buses once baby arrives. Would be interested in hearing anyones experiences of this type of chassis, any pros and cons etc. Thanks!
