Review: Love and easy to install!!! - We couldn’t be happier with the Britax Poplar. After struggling with other convertible car seats, this one was a breath of fresh air — the installation was incredibly simple and took just a few minutes. It clicked in rock-solid on the first try, which gave us so much peace of mind. The seat feels sturdy and well-built, yet it’s surprisingly compact — it fits easily in our back seat without feeling bulky, and still gives our child plenty of room. Our little one seems super comfortable in it, and we love the extended rear-facing option so we can keep them safer longer. It also has thoughtful details like easy-to-adjust harness straps and breathable fabric that keeps our child cool. For the quality and safety features, the price felt really reasonable too. Highly recommend — this seat has made our daily drives so much less stressful!
Review: Clicktight feature is amazing for safety!! - 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).

### ⭐⭐⭐⭐⭐ LOOK NO FURTHER!
*by T***K on November 5, 2025*

I don’t normally write reviews but omg I had to do it for this. When I started researching car seats i originally went with the Graco 4ever dlx and my baby absolutely hated it! She normally is fine in her infant car seat but with that one in particular she screamed every time. So I did tons of research and finally landed on the Beitax Poplar S and it is AMAZING. Firstly, it is insanely easy to install. Second, it is great quality and extremely cushioned for comfort. My baby is so calm in it (more so than she is in her infant seat)and falls asleep almost instantly. I really appreciate having the anti rebound bar as well. You can rear face for up to 50lbs which is about 10lbs more than most other car seats. Also, it fits perfectly into my Jeep renegade. The only thing that is possibly a downside is that it is heavy from the steel frame but even if you were to switch it between cars, it’s so easy to install that it pretty much makes up for the con of the weight. I’ll forever buy this brand of car seats for all my future kids. Hope this helps!
