@chrisss7 I tell everyone that I advise to get a car seat with a base. So many baby appointments and in general going in and out of the car is so much easier and convenient than latching or strapping each time. So I would not get the urbn car seat.
If you want Nuna car seats, get the Pipa RX. If you want an Uppababy car seat, get the Aria if you aren’t expecting until after March since it comes out in March. Both will work with an Uppababy stroller (if adapter for Nuna Pipa RX) but only Pipa RX will work with the Nuna stroller.
Now more specific to your question, Vista or Triv? It is very different, I would say Cruz Vs Triv is a better comparison as they are closer in size. Vistas main draw is two child sitting. But if that was your main point then you wouldn’t really consider the Triv. I also was debating heavily between Cruz and Triv. My buddy went with the Triv and I went with the Cruz. They haven’t had their baby yet so I can’t tell you their thoughts on it but what drove me to the Cruz was mainly the sturdiness of the stroller. It felt like it could last through a second child if needed. I could’ve gotten the Vista but seemed too bulky and heavy for my wife’s liking and the steering when you have two isn’t as smooth so we decided to just focus on one child’s experience instead of planning for a potential future. The Triv felt like it wasn’t as sturdy or suspensions weren’t as nice. Also it’s a single point of failure if that middle pulling contraption doesn’t work, you can’t fold your stroller. The demos as multiple stores I checked, the Triv folding either didn’t work as easy as others or got stuck. I’m sure it’s been abused but just made me not want it for the longevity of it. Cruz I feel like I can use it for way longer and Triv felt like it would not be as seamless down the line.
The other big issue I had with the Triv is the storage space under the seat. It only holds 10 lbs while the Cruz/Vista holds 30 lbs and bigger area. This is a big difference and even with just my diaper bag in the storage bin on the Cruz, it fills up a good amount so I can’t imagine the Triv storage being enough for any all day adventures or much.
Those are my two main issues that drove me to get the Cruz over the Triv. I spent days researching to the point I knew more than the Nordstrom reps and going back and forth between the two. I’ve very happy with my Cruz choice and Pipa RX combo. But if I had my baby after March this year I would’ve gotten the Uppababy Aria for a lighter car seat and handle bar ergonomics for holding the car seat.
Good luck with everything! I have tons of doubts in my choices so I understand your mindset, both are great options but just gotta figure out what are the dealbreakers for you between the two since it’s different for everyone.
