BEST CARSEAT!!!
Been a Britax fan for over a decade when the roundabout was my favorite convertible seat. I just love the quality of this brand. Itâs 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 itâs the absolute perfect seat. Get it you wonât regret it you will if you donât.

Happy Toddler, happy siblings and great road trip+
We love britax! This was the best choice for our toddler. We are a sports family who is always on the road. And we travel 12+ hrs to a destination. Its built with all steel framing that is what we were looking for and this is what we got. It is super easy to install and adjust. The safety is the best when it comes to britax. Functionality is great. It looks and feels nice. My baby is a sweater and there are no stains we’ve had this for 5 months. Cleaning is simple or a simple youtube short. Best bang for your buck. The best!

Best quality car seat for an affordable price!
I am impressed at the quality of the car seat. It is definitely heavier (sturdier) so you wonât be lugging it around but it is by far the best car seat around. The shoulder pads and the buckle pad are thick. It is very easy to tighten and loosen. Baby fits in it perfectly. The install is SUPERIOR to any other car seat. I feel confident knowing that the car seat will protect baby in case anything happens. I will never buy a different brand of car seat again. I know there are a few that convert into booster seats but I donât think it is worth sacrificing the safety that is needed when theyâre younger. Booster seats are inexpensive. Iâd rather purchase this one that fits and protects nicely in the first few years of life, and then later on purchase a booster. I love that baby is able to rear face longer as well. There is a level on it too so you know when you have the car seat reclined just right.

Love it so far
I will say that installing this car seat at first was a bit difficult and confusing for me, but I watch Britaxâs video tutorials on youtube which helped. Now that Iâve uninstalled and reinstalled it a few times, I find it very easy. I love the click tight under the seat, it works great. The car seat is so secure and doesnât move an inch. I find the adjustments very easy to use as well. It is very cute, and fits decently in my compact sedan (Chevy Cruze). It seems pretty comfy too.I, thankfully, canât actually attest to the safety of this car seat, but Britax is highly rated in that department from what Iâve read. And I did a lot of reading before making my purchase.Overall, I really do like this car seat and recommend it. First time installation was difficult, but once you figure it out it is much easier. ðð»

Didn’t know I could love a carseat so much!!
I didnt know it was possible to love a car seat so much. Installing takes literally seconds with the easy latch system and it is SO SECURE!! Like it seriously doesnt budge an inch. Love that it has two cup holders and is super comfy for my kiddo. Taking all the pieces off to wash is a bit of a project, but not that big of a deal. Its a little annoying that the shoulder pads dont come off for washing (at least I’ve tried a bunch of times and dont think they can???) BUT they got completely clean with a quick washcloth scrub so I am satisfied with that. I feel like my kid is totally safe in this seat!!

Great quality, just 1 minor flaw
Weâve been using the Britax Poplar S for a little while now, and overall, itâs a fantastic car seat! The materials feel high-quality, and the steel-reinforced frame gives me confidence in its safety. Iâve seen a lot of reviews complaining about the weight, but honestly, thatâs to be expectedâit has a steel base for added protection! If you want a lightweight car seat, youâll likely be sacrificing durability and safety.The only reason Iâm 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!

Great car seat!
The best slim fit car seat there is. Easy install with multiple recline levels. The seat itself is fairly light in comparison to others we have used. Love that the seat belt gets locked into place underneath where your kid sits. Material is nice and easy to clean if needed. Manual is easy to read and helpful with install instructions

12 month old loves it
Our 12 month old loves his new car seat. We transitioned to this car seat after using the Clek liing infant car seat, which we also really liked. We researched the current options throughly and settled on this one because of crash test performance, the fact that no flame retardants are used, and the slim design. There was no smell to the materials on unboxing and it was very easy to install. The seat fits in our sedan well and our son looks very comfortable when sitting in it. I also like the peace of mind with the anti rebound bar. I am very happy with this purchase and I feel that it is an excellent value considering the quality of the materials and the features of this car seat for the price point. We have not washed the cover yet but the material wipes down easily.
