Side Impact Protection

Two layers of Side Impact Protection help keep your child safe during a collision with an energy-absorbing shell and foam-lined head rest.

Impact Absorbing Base

Compresses to absorb crash energy and counteract forward movement keeping your child clear from the seat in front of them.                    

Quick-Adjust 10-Position Harness

Allows you to easily move the harness upward and buckle outward for a comfortable, secure fit as your child grows.

3 Recline Positions

Make it easy to find the proper angle for secure installation and your child's comfort.

Designed with superior safety and excellent comfort, the Boulevard Convertible Car Seat is an exceptional choice for getting your family where they need to go. SafeCell Impact Protection surrounds your child in safety components that work together to protect well beyond the established federal safety standards. The Boulevard features Complete Side Impact Protection PLUS providing an advanced layer of protection with a deep protective shell and an energy-absorbing foam headrest designed to keep your child?s head and neck extra secure.

A car seat works best when the harness has the right fit, so we include the Quick-Adjust, 10-Position Harness that grows taller with your child at the push of a button, as well as the Click & Safe Snug Harness Indicator to take the guesswork out of adjusting the harness to the proper tightness. The 2-Position Buckle gives your child room to grow and Plush Foam Padding provides premium comfort at every touch point. Installation is made simple with Easy-On / Easy-Off LATCH Connectors that lock into place with an audible click and are easily released with the push of a button. There are even 3 Recline Positions so your little one can relax at the right angle.

The Boulevard converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) and has been carefully designed to keep your little one safe and give you the confidence to simply click them in, give them a kiss and go.

Best Convertible Carseat!

This carseat is THE BEST! It's easy to get a solid install in the car both using LATCH or the seatbelt. Built in Seatbelt kickoffs for forward and rear facing. Steal frame makes it a solid carseat. Very easy to get the child into the carseat tightly both forward and rear facing

My now 3 year old has been in this car seat since about a year and is still comfortably facing backward in it. It is easy to move in and out of the car, install, and fasten. It is used in a grandparent car so they remove it frequently when he's not with them. He has been in it for road trips and been comfortable and it is easy to remove him if he is asleep.

This is an okay carseat. The top side impact pieces feel like they are so flimsy they could break. Fabric gets baggyish after a year of use. I prefer the Diono Radian 3 RXT.

When it was time to upgrade my twins from infant seats last year, I researched multiple seats and felt comfortable that my best choice was the Britax Boulevard ClickTight. We purchased two last year during the Black Friday sale. This year, we decided to upgrade the seats for my momís vehicle. There was no question as to what seats we would buy. The Britax Boulevard ClickTight in Baxter was on a Black Friday sale for an unbeatable price. I feel much more comfortable now knowing my girls are in such safe seats in my vehicle, as well as my momís. I definitely recommend!
  • Easy installation
  • Click Tight let?s you know when the straps are secure
  • Seems to keep my girls comfy
  • Easily fits three across in a tahoe (2 britax boulevards and a graco tranzitions)
  • Our first set, we were able to get girly prints for a great price
  • This time around, only the baxter print was on sale for so low

Our Britax Boulevard G4.1 Convertible Car Seat has been great for over 2 years now! We feel it is very safe for our children and are purchasing additional ones for our newest addition. As people mentioned the bottom buckle is quite short but it works ok for us since our daughter is slim. Could be better which would make this a 5 star seat! Still highly recommended! Also, Albee has been great for our family baby gear purchases!
  • Great safety!
  • Bottom buckle is short and would be nice if it was just a little longer.
Solid choice to keep little ones safe
By Ben

This seat arrived battered. Box was pretty much destroyed and I was sure the seat would be at least cracked. Upon opening and inspection the seat was surprisingly intact. I suppose these are built to take some abuse. Had this been my primary seat, I would have had more concern, but this was for my grandma to use occasionally, so no big deal. My local delivery services typically deliver battered packages, so I don't suspect it left the seller damaged.

I have the ClickTight version for our main car seat, so I'll comment on the trade offs. ClickTight is much easier to install and switch vehicles, so if you need to move it around I would recommend upgrading. This model is a bit clumsy finding the hidden lever to release the restraints, whereas ClickTight has a clearly marked recessed button. ClickTight also has a fully adjustable recline setting to match the child's needs as they grow (ie not letting their head slump forward as they sleep). This model only has 3 recline positions, so if your seats are buckets or abnormally flat, they may not be an ideal angle and you'd have to space it by stuffing a rolled up towel under it. I've only installed the seats in cars with built-in baby seat anchors, but threading a seatbelt through this model looked fairly confusing in the instructions, which were not written for someone to be able to understand while watching an infant. If using anchors, only install on the passenger or driver side. There are only a few cars on the market designed to anchor a seat in the middle seat.

I'd also recommend their infant seat. It was fairly expensive for the few months our 11 pound beast of a baby fit in it, but being able to quickly click a seat in and out was great. Never had to disturb her when going into restaurants so she could stay asleep, or grabbing her quickly to run inside in the rain. Using this seat in that stage would have been a pain.
  • Britax is a great mid-point where spending more doesn't increase safety, yet this won't alienate less fortunate families.
Best Uses
  • Since this is more difficult to install, it would be best used as a spare or for a family that plans to only use one car and one set of guardians. If you want grandparents to watch a child while seeing a movie or attending a wedding, keep in mind you'll have to leave time to swap the seat over to the grandparent's car, or trade cars with them. I tended to just risk it until I found a deal on this seat. I do not trust my mom to drive my Audi Q5 hybrid with her aloof driving record, lol.
  • It seems they sacrificed some features compared to ClickTight. Seems like they increased manufacturing costs the increase the markup gap, which is just annoying and petty.

I bought this for my grandchildren 3 of them were born in 2017 I watch 1-4 kids everyday so I need a safe car seat with EASY installation . This car seat is so easy to install I can take it out, transfer, and put back in my car with such ease. With gc #1 we used another brand that was & is a nightmare to install, I dreaded anytime it had to be moved. Britax is such a breeze not only do I use it (infant & convertible) but ALL of my children use it in the autos, as well as their in laws !

Great seat. Very happy. I had bought a cheaper brand but the chemical smell from the toxic fire retardants was overpowering as soon as I opened the box. I sent it back and got this one instead. So glad I did. I love that Britax doesn't use toxins. Also I thought the straps were too short at first but after removing the infant cushion there is a ton of room for my daughter to grow.

We got this carseat to replace a different kind we tried (different brand), that ended up being far too difficult to install tightly. Since we had success with the Britax infant seat, we decided to give it a go for a convertible, and I am so glad. Installation was a breeze. Quality is outstanding. My daughter loves her new carseat, and so do I!
  • * Easy to install
  • * Unbeatable quality
  • * Best rated for safety
  • * Cute zebra print
  • * No cupholders (honestly doesn't bother me considering how good this seat is)
  • * Heavy (but SOLID, so again, minor quibble if you're planning on transferring to and from cars. Ours will stay put, so not a 'con' for us)

Bought this seat for my 1 year old to continue to rear facing in once his rear facing only seat is outgrown within the coming weeks. I debated between several seats, all had their own pros and cons, and chose this one mostly because I liked the cover the best. When I installed it, my 4 year old wanted to rear face in it and he was the first one to use it. Very comfy, fabric feels easy to clean, which is a plus considering it's hand wash only. Fit well in my vehicle with my other two kids even though it's not super narrow. Being a CPST, I get hands on with many different seats, and this is one I personally liked for my child and situation and budget.Please consult a child passenger safety technician or the seat manufacture if you have any car seat related questions.

  • Allows for extended rear facing
  • Easy to install
  • Not super heavy
  • Range of allowed recline (manual position 3 required rear facing) rear facing.
Best Uses
  • Extended rear facing to keep a child rear facing past their first birthday.
  • Lock-offs difficult to close
  • Not as much leg room as other seats but it's not a huge concern, my 4 yr old didn't mind it

By MDMama

I got this seat for my 2 year old as a replacement for an older one that was about to expire. This was a great price but I wish I'd known that the manufacturing date was 2016 because that means one less year of being able to use it, according to Britax's expiration dates (if I understand them correctly they go by manufacturing date not when the seat went into use). The seat itself is great and Albee has a really good price, especially on sale. The zebra striped fabric is shinier than I realized it was going to be, but it is still fun. I have always used Britax seats and am comfortable getting a tight install with the latch connectors so I wasn't interested in the Click Connect new kind.

Removable cover!
By Daniella
from Arlington, Texas
on August 1, 2017
Verified Buyer
I really wanted a car seat that was rated to have low-chemical content, with a removable, washable cover, that was safe and easy to install. This met ALMOST all of my wish list. It's cute and seems comfy and the price is great on sale, but I found this so difficult to install compared to my Chicco NextFit Zip. I didn't buy another Chicco NextFit Zip because it has a poorer chemical rating, but compared to the Chicco this car seat took a lot to maneuver to sit in the car correctly. The strap adjustment was also difficult, and the seat itself doesn't have a nice recline option like the Chicco. It seems to be a little too upright in the rear-facing position, and when my toddler falls asleep in it (he's 18 months old) I notice that his head falls forward sometimes. Overall, I think this was a good purchase, and I could deal with the seemingly more complicated install. However, to improve my rating, I would ask that this be redesigned to have more of a recline option.
  • Britax - great brand
  • Price - on sale this is a great deal
  • Style - cute. Who doesn't love zebra?
  • Comfort - seems cushy and has soft velvet material
  • Cleaning - easy to remove, washable seat cover
Best Uses
  • Long term use due to low chemical rating, easy to clean (cover removes and is machine washable)
  • Install - this seemed to be difficult for both my husband and I to install (but let's face it, all car seats kind of are....)
  • Recline - haven't tried forward facing yet, but in rear-facing this seat seems to be too upright. Toddler's head falls forward when sleeping (scary!)

We are huge Britax fans, but this seat is very disappointing. We used this seat for only a few weeks before the cover began looking very worn. The material has terrible snags all over it and looks awful. I would recommend Britax products but definitely not this particular one.
