Raddl Reviews
Small seat with BIG LOVE!
We wanted to wait for this review until after our big up-north trip, and I am SO happy I did because it was AMAZING! My daughter who NEVER naps anymore since being forward facing, napped half the trip because she was so comfortable! The ClickTight installation system is a game-changer. It makes installing the seat so easy and secure—no more wrestling with seat belts or worrying if it’s in right. The built-in lock-offs and LATCH connectors are straightforward, making the whole process quick and hassle-free. My daughter loves this seat! It’s super padded and comfy. The adjustable headrest and harness will grow with her, so she’s always snug and happy. Plus, there are multiple recline positions for rear-facing babes. The Britax Poplar has a nice compact design. It’s roomy enough for my daughter but doesn’t take up too much space in the car. It would definitely fit well in smaller cars, and even in our large SUV we needed a seat that could fit with multiple in the 3rd row. Overall, I’m super happy with the Britax Poplar car seat. It’s easy to install, super comfortable for my daughter, and fits well in my car. Highly recommend!
I wish I had this seat three years ago!
I have been a fan of Britax since I purchased our first Britax three years ago. When Britax came out with the Poplar, I knew I would be a fan. We needed a convertible seat for our 10 month old and this was the perfect choice. I am so impressed the comfort, sturdiness, and extra convenience features this seat has.
