My almost 3 year old has not outgrown this seat, although she has just learned to unbuckle herself!  Really, I feel the $300 investment in this seat was well worth it.  We have other "cheap" seats that cost about $50 for the other vehicle we drive and the sitters.  There is no...

Pros Comfortable
Cons Heavy, difficult to install
Recommended it? Yes

I got this seat for my 6yo because he was outgrowing his carseat and was not quite ready to be boostered due to sensory issues and poor impulse control. Installation was a bit dificult but I figured it out with the help of a car seat tech. My son appreciated being able to remain harnessed for a... Read full review »

Recommended it? Yes

I have 4 boys and I think we have owned every car seat on the market.  The Britax Decathlon has been one of my favorites.  It is a very plush, strudy, heavy car seat.  I feel good knowing that my boys are safe riding in these seats.  That said it is a very big seat.  It is... Read full review »

Pros Safe, Durable, Great Design
Cons Bulky, Difficult to Clean
Recommended it? Yes

We were actually in an accident with our daughter in this carseat. We rear-ended the car in front of us and I am so happy she was in this carseat! The only thing that happened to her was that the straps left red marks on her shoulder, but she had taken off the shoulder pads that would've prevented... Read full review »

Pros Safe, Comfortable, Easy to Use
Cons Heavy
Recommended it? Yes

This is a great car seat made by a very reliable company.  However, while Britax seats used to be head and shoulders above the competition, that is no longer the case.  In the past couple of years, other companies have gotten on board with producing very good carseats, and Britax seats...

Pros Safe, Durable
Recommended it? No

This was a seat that we replaced after using it for a year.  Britax is a very safe and highly trusted brand so I felt very good having a seat made by them. 

I was most excited about the shoulder strap adjustment being such that you don't have to un-install the seat to adjust... Read full review »

There is nothing like a Britax.  I am even more a believer as we were in a sustancial car accident just recently.  I purchased my Boulevard for my special needs child as he has a neurological condition, and I was mentally wanting protection for my child in case of a side impact.  We were rear ended...

I originally purchased a different car seat before I bought the Britax Boulevard. I am very impressed with this seat. It is very sturdy, and I found it very easy to install. It has true side protection, it reclines and has adjustable straps and the weight limit goes up to 65 pounds. Another bonus... Read full review »

Pros Durable, great constructions, lasts through child growth, easy to clean.
Cons Can't use to bring baby home from hospital. Need infant seat for first day.

This is on the expensive side for car seats but well worth it! This seat lasts from infant through riding without a car seat. I would recommend the investment to anyone, the baby finds it comfortable and it grows with your family. Easy to clean and very durable! Also this car seat was very easy to... Read full review »

I have owned a Britax Boulevard for a couple of years now and I love it. The seat is nice and plush, my son falls right to sleep in it. I like how you can adjust the shoulder strap height without having to rethread the straps through the holes like in other car seats, all you do is twist a knob and... Read full review »

A truly useful convertible car seat

Pros Great, easy adjust features.
Cons Costly (buy on e-bay and save $$$ about 75!)
Recommended it? Yes

I have owned a total of 5 car seats so far, and 2 of them are Britax Boulevards, and I'm about to buy a 3rd. (I've also had the Graco safeseat step 1 and 2, the Eddie Bauer all-in-one and the Evenflo Triumph) and the Britax is way more expensive than any of the others, but justifiably so.

Protecting your child from a car crash is something you think about even before you give birth because it’s often one of the most expensive items on your “To Buy” list of baby gear. In reviewing various websites and guides, one name repeatedly comes up: Britax.

Pros safety, easy, Great head rest.

Even though this seat is quite pricey, it is worth every penny. My son is very comfortable in it. My favorite feature is the side head protectors. They are not only good in a crash but my son uses it as a head rest when he sleeps, so his head does not flop around like my other car seat (cosco alpha... Read full review »

I've had this seat for 2+ years with my firstborn, and have absolutely zero complaints, which for me is amazing. It is very safe, comfortable, attractive, easy to use (the one tiny nit I have is getting the buckle out from under my toddlers bottom every time he sits down). I have 2 other... Read full review »

Cons Rear-facing leg room and poor customer service.

When I purchased this product, I did so because my 8 month old was 29" and her infant car seat's maximum height was 29", so I thought I'd go ahead and buy a convertible to use rear facing until she turned one. We have a Yukon with bucket seats in the back, and when I installed the car seat, I... Read full review »

Pros Doesn't move an inch when latched into the car, large, hefty, and rock-solid
Cons Very bulky and heavy. Don't try to fly with this monster carseat.
Recommended it? Yes

I'm not a person who goes out and spends extra money on the kids. However, the Boulevard carseat is so hefty and strong, and latches into the car so rock-solidly, that I don't second-guess the money we spend on these.

We originally got our Boulevard carseats for my daughter when she... Read full review »
