  • Excellent car seat
Color: Glacier Graphite Style: Poplar S
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. ... show more

  • Worth every dollar.
Color: Glacier Graphite Style: Poplar S
Very happy, bought this for my grandson to grow into for years to come. Can't be the value, he can growth and have plenty of room. You can travel long distance and there is so much padding he's more then comfortable and I know he's really secure in this seat. After we got the seat so hooked in, I know this seat not going anywhere in an accident!!! It's so sturdy, secure, soft, well made, I couldn't be happier. Only down side is it's heavy so I wouldn't want to move it from one vehicle to another all the time. Plus once it's hooked in, it's in. I'm not unhooking it lol but I really like this and know my grandchild is very safe so to me that's with every dollar. ... show more

  • Wouldn't choose anything else
We absolutely love these seats, we have the pink and grey ones, they are so comfy and we can fit two with a booster in the back of a Corolla easily, but they aren't narrow or hurting the kids hips. Our kids wanted to be strapped into them just to watch TV while we were setting them up because the padding is so cozy. They're durable and a bit on the heavier side, but super easy to install. I'd venture to say they're probably safer than our old Graco's, based on how durable they are alone. They FEEL safe if that makes sense. This is not a flimsy seat at all. They fit both our toddler and 6yo well with no issues. ... show more

  • Fixed the problems with the Boulevard! Great car seat!
Color: Glacier Graphite Style: Poplar S
We have the Boulevard and loved the installation. This car seat is the same click tight mechanism and is super easy to install. The main complaint with the Boulevard was the location of the harness release. The Poplar harness release is a bit of a maze to find initially but is in a much easier to reach location. The seat fabric feels soft and there is plenty of padding for smaller babies. Overall, this car seat is built great and is very comfortable for our child! We've bought multiple for our multiple vehicles. ... show more

  • Amazing car seat, 9/10 but pain to dissemble to clean
Color: Glacier Graphite Style: Poplar S
Love this car seat! My daughter loves it too, super comfortable for her and it’s high enough she can see out the window when driving. It’s very secure. Only downsides are it’s HEAVY (which I guess could be good for safety reasons) and when taking apart to clean it, it’s a pain to take apart and put back together ... show more

  • Britax fan for life
Color: Glacier Graphite Style: Poplar S
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 ... show more

  • 12 month old loves it
Color: Glacier Graphite Style: Poplar S
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. ... show more

  • 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 ... show more
