It's not even *that* different, I just love that little seat haha... it looks like you could put a pretty young baby in it quite comfortably. I hate seeing 6,7, 8 month olds going around the theme parks for 12 hour days in car seats in the sit n' stands because the seats are too upright. This looks like a nice solution and so much nicer for baby than being in a car seat for hours in order to sleep or face mom. The different models have different pictures but it seems that you can put a Snugride in front or back and it sits nice and high up in the rear position. Pretty cool so far, can't wait to see how it works out for people. We desperately need a decent sit n' stand stroller on the market! the concept is great but so far they all pretty much suck.
