I read hundreds of reviews and watched countless YouTube videos about double strollers. My toddler (just turned 2) is very large for his age and is 37" tall and almost 35 pounds. He's going to need a fully functional stroller for at least another year, because we like to take him tons of places (Disney, zoos, etc.) The obvious problem is that he's already at the max for a lot of strollers. We decided to try out the city select lux and this one. The lux was just too small for him already. The seat on that one is about 18" tall and 12" wide and both are that size. His head was at least an inche above the seat back already. He didn't mind and found it comfy but he would quickly outgrow it. Also, the footrest area was already too short for his legs. I could position that one only with him facing toward me on the bottom and the carseat on top. It wasn't a problem for him, but that was the only option with the Chicco keyfit attached. With both seats attached, he didn't have any leg room if I put him at the top and his legs were against the bottom seat. For over $800, this stroller was not practical. If you have smaller kids though, it was a nice stroller. The Vista is perfect. He has 2-3 inches of headroom and legroom left in the toddler seat (You can see where his feet hit in my first pic but note that the canopy is on the low position so it's closer to his head than normal. It moves up 3 inches to give more headspace!) He also fits in the rumble seat (see my 3rd pic). The back of the toddler seat is about 21" and rumble is about 18". The Vista rumble seat and Lux seats are all about the same size. The best part is that I have many choices of positions between the seats and attachments. The keyfit 30 can be placed on top or bottom with my toddler also in there. You can see in the first pic that there's even room to recline him several notches when he's on top! When he's on bottom, the rumble will still face in either direction!!! And I can recline it one notch facing out! Facing in, it can be reclined all the way. (The last picture with the diaper bag shows how the rumble foot rest fits in the basket. My son loves this! And even with his feet in there, there's still plenty of room for the bag and more!) Side note: the bassinet only fits in the bottom with toddler facing me, but that's fine! I thought I would be uncomfortable with the baby on the bottom, but as you can see the bottom position is not lower down than most regular strollers! (I have upper and lower adaptors on.) I actually like the carseat on bottom! The new baby will be very protected in there and it will be harder for random people to touch her. (Another note: I tried all of this with a life size newborn doll because my daughter isn't born yet lol) The stroller is very nice. Even with my toddler in the front, it pushes like a dream! I can push it with one finger with him in the front and the carseat up top! The bassinet is really nice too. I plan to use it mostly around the house, but for longer day trips it'll be nice to have for diaper changes and to give her stretching room. It's super easy to change seats and attachments. I don't find it too heavy (even while pregnant). The only thing I wasn't expecting is the rumble seat has it's own adaptors and the carseat holder and bassinet use the lower adaptors. You'd have to change to switch between these things (but it takes only a minute or so!) The toddler seat holds 50 pounds, the rumble 35 pounds, bassinet 20 pounds, and basket 30 pounds! And I almost forgot, yes, you can face both seats out comfortably!
