  • Clicktight feature is amazing for safety!!
Color: Magenta Onyx Style: Poplar
Amazing car seat! The click tight feature is amazing, I had a problem with other car seats being too loose once installed in the middle seat (you know how it can only move an inch at the belt path, or else it’s not secure). After doing some research I decided to try Britax because of their click tight feature, it solved my problem right away.The click tight feature expertly secures the car seat in the car with no movement at all it’s rigid right in the car seat which is perfect and I don’t have to worry about the car seat being too loose now. Safety and comfort 10/10! I wish I knew about Britax and Clicktight sooner! A must for tricky middle seat installs or when you have a hard time getting a seat to be secure in the car this will solve that problem. Also since I’m obsessed with safety I love that you can use this in rear positioning until 50 lbs (since rear seat positioning has been shown to be the safest). ... show more

  • BEST CARSEAT!!!
Color: Magenta Onyx Style: Poplar
The media could not be loaded. Been a Britax fan for over a decade when the roundabout was my favorite convertible seat. I just love the quality of this brand. It’s very sturdy, easy to install, Clean and most importantly extremely comfortable for my babies. This is my second purchase of the poplar and I love the slim profile makes fitting two in the back of my Honda ridgeline a breeze with room for another passenger. No cons for me it’s the absolute perfect seat. Get it you won’t regret it you will if you don’t. ... show more

  • Love this seat
Color: Magenta Onyx Style: Poplar
Super easy to install and it doesn’t budge. It’s slim fitting I have a regular sedan and it’s not too big for my car. All around nice seat and well worth the price. I did alot of research they’re very safe ! The click lock with the seat belt makes it so easy to get the seat tight without any movement. ... show more

  • Best seat to transfer between cars!
Color: Magenta Onyx Style: Poplar
I absolutely LOVE this car seat. It’s comfortable for my daughter, and it’s so easy to install and move between cars. I timed myself and it took me 1 minute 13 seconds to switch it between cars.

  • Comparison with the Nuna Rava
Color: Magenta Onyx Style: Poplar
I bought this to replace a 6 year old Nuna Rava that broke. Back when I bought the Rava in 2018, it was one of the only 50lb rear facing limit car seats and had the easiest installation. Of course, other car seat manufacturers would be following suit soon enough. This car seat is an excellent and more affordable option for those looking for the Nuna Rava. It actually is better, in my opinion because it: - is practically half price - has removable cup holders - has a removable and washable cover - has easier to tighten harness straps (I swear I had to injure my shoulder to get the Rava straps tight enough, especially in colder weather) - has a better way to hold the harness straps and buckles to the side as you're loading in your baby Literally the only things I don't like about it are the same two things with all Britax car seats (I have two other Britax for my older kids): they're super heavy and the harness straps release button is hard to locate and activate. I used the Rava for 6 years, and it served its purpose well. But I'm kinda glad it broke (user error, not the car seat's fault) because now I don't have to injure myself getting my kid strapped in properly. This car seat has the two things I chose the Rava for: the 50lb rear facing weight limit and the super easy installation. But it's less expensive (in no way "cheap" though) and easier to use. ... show more

  • Best car seat for small spaces!
Color: Magenta Onyx Style: Poplar
Someone said this car seat fit in a smaller car so I bought it. This car seat fits in my Tesla Y with my husband driving and my third row seat in use. It fits so well. The car seat is easy to wipe clean and it’s super nice quality. I love how easy it is to buckle in rear facing. It is also easy to uninstall once you figure it all out. I had to really look a couple of times at the manual to figure it out. It is heavy but so easy to install once you move it to another car. The heavy doesn’t bother me as much as I thought it would. I’ve had many car seats over the years and I loooove this one. ... show more

  • By far my favorite
Color: Magenta Onyx Style: Poplar
This is my favorite carseat. I research carseats to no end before purchasing. This one checks all the boxes for function and safety. It is not to big but not to small. I can fit two other carseata next to it without any issues. It is high quality and super safe. My daughter has been in it as a rear facing and forward facing. It was extremely easy to move from rear to forward facing. It is also easy to clean since the material is similar to swimsuit material. Highly recommend! ... show more
