Description

Ready to go with room to grow! The Britax Poplar Convertible Car Seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight® Installation and slim SpaceSaver™ design. This car seat accommodates up to 50 pounds rear facing to help keep your child riding safely even longer and easily switches to a forward facing car seat as your child grows. ClickTight Technology installation provides fully open seat belt paths that are clearly labeled and easy to access, and the automatic tensioner takes care of the tightening. Slim outside and spacious inside, the toddler car seat features 17" SpaceSaver technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort. The Britax car seat boasts a patented SafeCell® crumple zone and V-shaped top tether to help manage crash energy. The reinforced frame and belt paths provide strength and stability. Rear facing car seat cover fabrics are naturally flame retardant with no added FR chemicals and safe to machine wash and dry. *Britax cannot guarantee 3-across installation fitment in all vehicles

Recommendation – Britax strongly recommends:

  • Children ride rear-facing to the highest weight or height specified
  • Children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed
  • The top tether be used at ALL times when installing the child restraint forward-facing.

Best in class slim car seat
May 5, 2024
Extremely comfortable, slim, and compact! I needed a car seat that was compact enough to RF in the third row of my SUV and decided to buy to see if this was more compact than our E2F, it is! It has such comfortable and soft padding and it was an absolute dream it install It’s as simple as buckling a seatbelt and pressing down on a door. Would recommend this seat to anyone.
Pros
  • compact, comfortable, slim, easy installation.

Spacious for a 17" seat
March 19, 2024
I was VERY surprised with how spacious the seat is for my 5yo with it being a 17" seat. The harness strap tightens and loosens like butter; however, Britax is sending me a new seat due the the straps slightly loosening over time (about 1/2" while driving). I am hoping that the new seat is just as easy to tighten. I'm overall impressed with the quality and really only have one complaint. I just wish they would've put the recline lever on the side with numbers like the One4Life instead of at the front of the seat. Install is so much harder having to move the seat to adjust and then not know how much I have adjusted it since there is no indicator.

Affordable, Narrow, Easy to Install Perfect Car Seat
February 25, 2024
We have loved Britax for many years however had to switch to a different brand when I needed to fit 3 across in the back of a Tesla Model 3. Unfortunately, I just never could get a good install with another brand specializing in narrow car seats. I am so incredibly happy Britax came out with a new car seat. With 3, soon to be 4 kids in car seats, it is very important to me that we have safe, easy to install seats. I just bought 3 of these seats for the Tesla and tempted to buy more to replace my current seats in our SUV. Easy to install securely and very narrow for a full feature Britax seat. I am a veteran mom and cannot express how excited Britax releasing these seats made me. We have owned 10+ car seats over the years as I do not like moving seats between cars and grandparents cars --- this Poplar is by far my favorite; even compared to other seats I have that cost nearly twice as much!
Pros
  • narrow, easy install, inexpensive

Car Seat for our 1 year old
February 20, 2024
We recently purchased the Britax Poplar for our one year old. We have a mid size 3 row SUV and it fits perfectly in the middle row. It takes up less room than her infant seat and my husband is able to move the driver's seat back more than he was before.
The seat itself is heavy and sturdy. It is pretty easy to install, as well.The cushions are really comfortable. My daughter can easily fall asleep in it. We use it rear facing. Definitely recommend, especially if you are looking for a safe and compact 3 in 1 car seat.
Pros
  • We like everything about it!
Cons
  • No cons as far as I can tell after 2 months of use.

Fits perfectly
February 7, 2024
Definitely not as bulky as the standard Britax convertible, shoulder strap pads have a grip to prevent slipping, the new “click tight” button is easier to use and hidden under the padding, which protects it from debris (food particles). Fits very well in a large SUV and truck. Only flaw I have noticed is that the child’s bottom sits very deep in the seat when you do not use the extra provided padding, which is not to be used after a certain weight.

Easy to use narrow seat
January 20, 2024
We purchased this seat because we really like our Britax One4Life convertible seat, but find it very bulky. The Poplar is super easy to install thanks to the Britax ClickTight system, which is critical because we have to move our car seats around frequently. It is compact front to back when rear facing and narrow enough to fit three across with a Graco infant seat and adult in the back seat of our 2019 Toyota RAV4. The fabrics are cushy and easy to clean. We have no complaints after two months of use.
Pros
  • Compact, narrow
Cons
  • The ClickTight takes noticeably more force to close on this seat than our One4Life

Great Compact Seat
January 17, 2024
We love this seat! It’s super compact both front to back and side to side, but allows the child a good amount of space inside of the seat. My toddler hated sitting in the Rava but loves this seat. Install is super quick and easy, I love that you can have cup holders or not. We now have them in both cars for both children

Narrow frame
January 16, 2024
Easy to install and narrow frame allows for all the children to sit in the back seat. Would recommend especially if you have multiple car seats.
Pros
  • Britax quality, easy to install, frame

Pretty and easy to install
January 9, 2024
I just installed the car seat about a week ago but I am already impressed. I love the Clicktight installation. The blue is so pretty too. My 9 month old likes his car seat and is very happy to be out of the infant seat.
Pros
  • Clicktight

LOVE IT!
January 2, 2024
I love this car seat so much! I needed to fit 3 across or 2 together in my Expedition. This fits so well! I wish this was available when I was shopping for the other car seats a year ago. The installation is the easiest of any car seat I’ve owned so far!
Pros
  • Narrow, easy install, narrow front to back.
Best Uses
  • Extended rear facing. 3 across and 2 together.
Cons
  • Under 22 lbs it requires the use of a bulky infant insert.

Highly recommend!
December 13, 2023
I absolutely love this convertible car seat! I bought it for my 8 month old daughter who was getting too big for her infant car seat and needed a bigger seat that was also slim enough for our car. This was the perfect seat! I originally purchased one from Graco, and it just did not work for us as it was really uncomfortable for my daughter. After doing some research, we decided to switch to Britax and decided on the Poplar, and we 100% loved it and would highly recommend! It is made of really good quality and it looks so much comfortable than other brands we looked at. My daughter absolutely loves it! I also love that it is super easy to install, and the click-tight is super nice!
Pros
  • - comfortable
  • - good quality
  • - safe wash
  • - click-tight
  • - easy installation
  • - slim

No Headrest Comfort!
December 12, 2023
The headrest has zero comfort and definitely compromises the premium Britax comfort! It is pretty and seems like a space-saving option but I'm extremely disappointed with it and currently trying to return it.
Pros
  • Spacesaver
Cons
  • Lacks the Britax premium comfort that I have been loyal to Britax for. The headrest is disappointing.

Love this car seat. It fits in all the seats I've tried it in, super cozy and easy to install correctly with the seatbelt. Cupholders can be removed which is great for tight spaces or baby doesn't need.
