    • Britax family always
Color: Glacier Graphite Style: Poplar S
I have been a Britax fan since 2007 when I got my then 1 year old his car seat. Since then, I’ve only had Britax car seats. It continues as we have purchased car seats for our grand daughter. My daughter has two and I have two. One I bought had issues and Britax was x changed it no questions. This Poplar S is perfect for my jeep wrangler. The one for life is great! But it was struggle in my jeep for room. We have put that in my husbands truck and this Poplar S in the jeep. Best car seats, safe and easy to use. Won’t go with another brand. You won’t be disappointed. Fit is easy, install easy, it is a heavier seat, but not too heavy, and for me, if it’s too light, I would question safety… ... show more

    • High quality
Color: Sand Onyx Style: Poplar S
I was dead set on purchasing a Nuna Rava, however I was turned off by the nonsensical cup holder placement. This Britax Poplar car seat came up in my final search as a compact seat that was also high quality. Being so determined on the Nuna Rava, I half expected that I might return the Poplar S. However I was pleasantly surprised by the quality and design of the Britax. The fabric is super soft and the seat is extra padded. I was previously using a hand-me-down Safety1st car seat and it’s insane how better the Poplar quality is as compared to a $150 car seat alternative. This seat is compact and fits well in my Subaru Impreza Sport. Install was pretty easy but I will need to put a rolled up towel under the seat to even it out and use the rebound bar. Summary: I’m impressed by this car seat as a competitor to other high-end, pricier alternatives like the Nuna Rava. ... show more

Not only is this seat extremely luxurious looking and feeling, it’s extremely sturdy, seems easy to clean, installed so easily with the latch option (I’m sure seatbelt is easy too)! My baby fits so well in it, she is currently 6 months and the infant insert is amazing! I love that this will allow my baby to stay rear facing longer and will grow with her! 100% will be buying another when I have a second baby! ... 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

    • Comfy seat with easy install
Color: Arctic Onyx Style: Poplar S
My son loves this seat! It’s super high quality with a nice amount of padding. The install is a breeze with clicktight and it was very easy to adjust to the correct settings. We haven’t had to wash the cover yet which will be the final test.

    • Definitely a nice care seat but very heavy
Color: Stone Onyx Style: Poplar
Overall we have enjoyed the car seat. We have had it just under a month now. We wanted a car seat that could accomplish 3 things. 1. Extended rear facing option 2. Easy to install 3. Easy to adjust straps This car seat does fulfill these options for us. It has the highest available limits for rear facing. It uses clicktight technology so you aren’t trying to pull a ton to get a tight install. It also does not require rethreading the straps to adjust the level. These are the pros for us. The biggest two cons are that the car seat is very very heavy and the fabric part is difficult to get on and off. 1. The car seat is so heavy that it exceeds the lower anchor limits around 35lbs (check the manual for exact limit). This requires you to install with the seatbelt which is not much more difficult because of the clicktight technology but the latch system is so easy. We also were hoping to have a car seat that was easier to install so that it would be easy to switch the seat over to a different vehicle. Unfortunately because it is so so heavy, it is not convenient to do so. 2. Our first convertible carseat only had two fabric pieces to take off when cleaning was required. They were also easy to put back on. This has several pieces and lots of little loops and parts that you have to carefully retuck the fabric. That’s fine but I was not expecting it. We had to wash the cover fairly soon after installing the car seat since our toddler had a bathroom accident. TLDR: We are glad to find a car seat that worked for extended rear facing and that is easy to install and use. We were surprised by how heavy it was and the time it took to put the fabric back on the seat after cleaning. ... show more

    • Expensive but better made
Color: Ruby Onyx Style: Poplar S
I find the britax’s easier to clean when really dirty (spilled ice cream, vomit). I like the easy release clips for getting them in and out of the vehicle. The strap release also lock securely but easy to release so I tend to loose the straps the un buckle. Then it is super easy to get a baby in with looser straps and then securely snug. Seems like better fit for different jackets/ clothes so always the right restraint. ... show more

    • Safe, compact, comfortable, and easy install
Color: Onyx Style: Poplar S
This seat performs better than more expensive competitors (looking at you, Clek foonf) in terms of comfort for the baby and ease of install. Even my husband could figure it out! Also, I didn’t have to spend a bunch of extra money to make it work for an infant as the seat comes with all the pads you would need. I am able to fit three across in the back of our Subaru outback without issue. I waited specifically for the Poplar S to be released because I knew I wanted the anti-rebound bar. Out of my Graco slim fit, Clek, and this seat, we have a clear winner. ... show more
