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!

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!
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!

Excellent car seat
I absolutely love this car seat. It’s so easy to manage and move from car to car the click tight design is amazing! Best feature ever for a car seat in my opinion. I bought a Nuna originally, thinking that I would love that and I do but I love the Britax more, the Nuna is in the truck and the Britax is in my car. Easy to wash and clean and put back together. I would say that the britax is much easier to put back together than the Nuna was. We’ve had both car seats installed and used for a year now. When my daughter is ready for the booster, we will be getting a Britax! It’s sturdy, functional and has multiple recline options. Well worth the investment.

Britax fan for life
I spent a lot of time trying to find the perfect car seat and settled on this. I could not be happier with this seat. It was a little more than I wanted to spend, but definitely a good value for the money. The seat is very well made, very safe and very easy to install. The entire cover can be machine washed AND dried which is huge. It also seems super comfy and well padded. My baby seems much more comfortable in this than in the infant carrier. Very well designed and intuitive to use. I would buy another in a heartbeat

Great car seat
I saw some reviews that the shoulder pads don’t come off, which would make them hard to clean, but I just received mine and the pads are Velcro (see photos), so it’s very easy to remove and clean them. Overall, I love this seat. It’s easy to install, comfortable, and includes an anti-rebound bar. We use it as our travel car seat (we have the Nuna Exec and the Clek Foonf as our daily beasts and those are great too, but way bulkier to travel with). We also have a Graco Extend2Fit that we’ve used for travel, but it doesn’t have an anti-rebound bar, so I consider this our best travel car seat so far.

Great quality, just 1 minor flaw
We’ve been using the Britax Poplar S for a little while now, and overall, it’s a fantastic car seat! The materials feel high-quality, and the steel-reinforced frame gives me confidence in its safety. I’ve seen a lot of reviews complaining about the weight, but honestly, that’s to be expected—it has a steel base for added protection! If you want a lightweight car seat, you’ll likely be sacrificing durability and safety. The only reason I’m giving it 4 stars instead of 5 is that the harness straps can be a bit difficult to tighten. It takes a little extra effort to get them snug, which can be frustrating at times. Otherwise, the seat is comfortable, easy to install, and a great space-saving option for smaller vehicles. Definitely recommend!

Easiest car seat to install, which means you’ll install it correctly and keep your kid safe
Installing car seats is probably the worst part of parenting small children. And if you do it wrong (which you will, unless you have a professional install it), it’s a serious safety risk! Britax click to connect is *almost* easy to install. Takes me under 5 minutes now, compared to at least 15-30 with my Chicco keyfit infant seat latch connectors. This is my second Britax because of the installation ease and the Safe Wash fabrics that are free of PFAS and flame retardants. My first Britax is the One4Life, and the straps are annoyingly short and hard to tighten or loosen. The Poplar won’t last as long as the One4Life because it doesn’t have a booster option, but that’s fine. It’s less expensive, and the strap is longer and easy to adjust. It gets great safety ratings with the anti-rebound bar, which is important to me. But seriously, the Britax Click2Connect installation is worth almost any drawback. Now that I’m used to it, I can’t go back to wrestling with LATCH or getting the seatbelts tight enough.
