The Roundabout Convertible Car Seat is a smart choice for keeping your little one safe and sound as you head out on life’s travels. SafeCell Impact Protection surrounds your child in safety components that work together to protect well beyond the established federal safety standards. And Complete Side Impact Protection shields your little one in a deep protective shell designed to absorb crash forces and protect from debris.

A car seat works best when it provides the right fit so the Roundabout comes with a 2-Position Buckle to keep up with your growing child. 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. The Tangle-Free, 5-Point Harness prevents the straps from twisting making it easier to load your child into the seat and ensuring a safer ride. Plush Foam Padding provides premium comfort at every touch point and there are even 3 Recline Positions so your child can relax at the right angle.

The Roundabout converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-55 lbs.) to keep your child safe, comfy and secure for the road ahead.

  • SafeCell Impact Protection is an integrated system of safety components that work together to protect your child well beyond the federal safety standards. Including an Impact Absorbing Base and Tether, an Impact Stabilizing Steel Frame, and Complete Side Impact Protection. SafeCell means your child is surrounded in best-in-class safety.
  • SafeCell Complete Side Impact Protection surrounds your child in a deep protective shell designed to absorb crash forces and shield your child from debris.
  • SafeCell Impact Absorbing Base compresses to absorb crash energy and counteract forward movement keeping your child clear from the seat in front of them.
  • SafeCell Impact Stabilizing Steel Frame gives you peace of mind knowing there is strength where you want it most, through the spine of the car seat reducing forward flex and at the connection points to the vehicle.
  • SafeCell Impact Absorbing Tether minimizes seat rotation with a unique two-strap design and slows forward movement with Britax’s patented rows of stitching that ?give-way? one at a time in the event of a crash.
  • Quick-Adjust, 2-Position Buckle allows you to easily move the buckle outward for a comfortable, secure fit as your child grows.
  • 3 Recline Positions for your child’s comfort and safety.
  • Plush Foam Padding in the cover, shoulder pads and buckle surround your child in comfort at every touch point.
  • Easy-On / Easy-Off LATCH Connectors lock into place with an audible click and are easily released with the push of a button.
  • Tangle-Free, 5-Point Harness prevents the straps from twisting making it easier to load your child into the seat and ensuring a safer ride.

Great and Safe Britax Car Seat

This is the second Britax Car Seat I have purchased. I have two grandsons and both require a car seat now. This is a safe and reasonable priced car seat my daughter approved me to have in order to travel with the boys. I would recommend to anyone!

Great value for a safe car seat for secondary small car and travel
May 5, 2018
We bought this car seat to go in the car we use less frequently because this car seat has all of the high-quality features of Britax (side impact protection, no flame retardant chemicals, etc.) but wouldn't be as comfortable as one of their nicer car seats for long car travel. For that, we bought the Britax Boulevard. So far we've been really happy with this seat and it was a good deal on Albee. It also takes up less room in the room than Boulevard (plenty of space in my compact car) and is MUCH lighter, so we'll take this one on air travel.

Hoping this is as good as the one I bought 14 years ago.

Bought a Roundabout 14 years ago for a Granddaughter and then another sometime later. Great car seat and now buying one for Great grandson to arrive in June. Britax quality is great and this price was very good which helps Grandparents on a limited budget who still want really good quality and safety. we just trust the quality is still the same. Albee Baby is a #1 retailer!

AMAZING for travel!
March 14, 2018
I can't believe how amazing this car seat is. I also can't believe how this is not famous as the perfect car seat for travel! This is the THIRD car seat I have bought specifically for the purpose of being lighter weight to take on vacations and then easy to install in the rental car. We are also using it at home as a car seat for grandpa's car so he can pick up the little one from preschool sometimes. THIS THING IS AWESOME! Easiest install by a long shot of any car seat I have ever encountered. High quality finishes on everything. Comfortable for both my toddler and my preschooler. Much lighter weight than it looks, without sacrificing safety or quality. This is the perfect car seat. I love it so much. I only wish I had discovered it years ago rather than wasting money on the other seats I have used for travel (and grandparents' cars) in the meantime. Our "main" car seats are Clek Foonfs, because we wanted very narrow seats to allow three across in our smallish cars, but this one really gives them a run for the money, at a fraction of the price. Love it and will definitely be getting another one for grandma's car!

Britax Roundabout G4.1
October 27, 2017
I purchased a Britax car seat because my daughter-in-law had one and highly recommend the brand. I feel my grandson is very safe in the car seat because it's very well constructed and sturdy and has lots of padding. The fasteners are easy to use and snug up easily. I liked the car seat so much I bought an extra one for my son's truck so my son and daughter-in-law don't constantly have to move the car seat from one car to the other.
  • -sturdy
  • -well constructed
  • -great padding over the whole seat, even on the sides
  • -straps and fasteners have removable padding
  • -fasteners that attach the seat to the car are easy to fasten and adjust
  • -the cover is comfortable and we'll made
  • -the back of the car seat is not adjustable so doesn't allow it to conform to the slope of my car's seat, so I tuck a towel under the rear of the car seat base to raise it a little to fit better.

Great Value for Convertible Car Seat
May 17, 2017
The car seat is great. The padding is much better than other popular brands. The only drawback is the area for rear facing where you thread the seatbelt through. It's a little difficult to get the seatbelt through. However it does have the latch clips for the seat anchors you can use if you choose. Overall the car seat is a great for the price and exceeded my expextations.

We had a bit of a struggle to get it secured in the car. Once we figured that out, it's been a breeze. This is the perfect extra seat to go along with our Britax Marathon click tight, and it's more than half the cost.

This is my second car seat purchase so we could have one in both cars. We got the Britax Marathon as our first. They are basically the same thing, the Marathon just has more conveniences. I don't think the conveniences are worth the higher price tag. I like them better than other brands I've used. They feel much more sturdy and the seatbelt is smooth to loosen and tighten. I recommend the Roundabout for sure. Keep your eye for a sale though, there are always sales.

Got one with my first son and he is 3 now and it still is great. Got a new one on sale for my 6 month old when he soon outgrows his infant seat. We love how easy it is and doesn't weigh a ton since we move them around quite a bit. Love the quick latches to the seat and that it just isn't complicated but fits nice and safe.

It carries the name Britax which is synonymous to reliability, and this one didn't disappoint. It is seldom to find detailed a convertible carseat at this price point, but here's one. It doesn't have the frills of the higher end ones, but it is still very safe and comfortable. The cloth is mostly of the velvet type, but I turn ac on the car anyways so it doesn't really make my baby sweat much. Size is comparable to every convertible out there. I use it on our back up car.

I purchased the Britax Roundabout for my son when he was about 8 months old. He turned three last month, and we're still using it. I love it just as much today as I did when I purchased it. Every couple of months I take the cover off and wash it, and it looks brand new. The seat is extremely easy to install/uninstall in the car, and is much more comfortable than most seats. It's also very easy to buckle my son into.

Wish the harness worked better
September 9, 2016
I really like Britax products and we had the Bsafe infant carrier. When we transitioned our infant to the Roundabout we were disappointed with the harness. We struggle on a daily basis to get the harness snug enough. We like the design and fit. It seems like a really safe carseat, but struggling to get the harness snug is a big disappointment. I want to make sure my child is safe.

I love this one over the other two that we have

This Britax was a gift from my sister in law, I have loved it from the very first moment we used for our first child (our second is using it right now). So comfortable for the child, very easy to install, super easy to clean, not so heavy or bulky although if you want to fit three car seats in a small car is not the best option. Harness are very easy to snap in and out not like my other two car seats (different brands). If baby fall sleep looks confortable. I would use it for my third kid but it will be expired you then. Hopefully we could afford to buy only Britax!!

Bought this seat in 2014 for my 19 month old and easily installed it rear facing. He is now almost 4 and we just turned it around to forward facing. Love this seat, it has fit him very comfortably in the last 2 years. The cover is easy to wipe down, but also very easy to remove if there is a spill and it needs washed. Padding is still comfy even after 2 years of use. We will definitely be shopping for another Britax when he outgrows this one.

I bought this foryear daughter when she outgrew her carrier carseat (also Britax). After much research a couple of years ago while I was pregnant, this is the only brand that I am willing to stick with. Safety, versatility, comfort and color options. They have it all. The convertible seat can go either rear or forward facing. And still looks like the day I took it out of the box a year ago. Also, my daughter hasent figured out how to uncle the harnest yep, which to me means it hasn't loosen up at all. I lover this seat and the brand.

Great Seat!
June 2, 2016
We bought the Roundabout when I decided we needed a less expensive car seat for my husband's car but didn't want to sacrafice safety or a higher weight limit. My son has consistently been large for his age (90th percentile weight, 75th in height on average) so higher height and weight limits are important to me. I had looked at other brands even though I was pretty attached to Britax by this point (I have had a B-safe, Marathon and a Pinnacle as well). It allowed me to rear-face my son well into his second year. I found the seat easy enough to switch from car to car when needed and I found the harness easy to adjust despite being a little more work than my Marathon (obviously).

I have 4 children and have used numerous car seats throughout the years. My first Britax purchase was about 2 years ago after trying out many cars seats and being left with only disappointment and fear of safety in the event of an accident. My youngest daughter will be 4 in July and from the moment I installed my Britax and fastened my precious angel in, Britax gained a loyal customer. I trust my Britax with my childs life and I feel a sense of ease knowing that she is, in my opinion in one of the safest car seats made. The styles and many options are just icing on the cake. The construction and time spent on making the car seats fit a child comfortably in any position is a bonus to the safety features. I'm looking foward to my next purchase. Thank You Britax!!

I absolutely LOVE Britax products. For my first child, I purchased the roundabout once it was time to upgrade from the infant seat and I have absolutely no complaints. It's easy to install or move from car to car & my daughter never complains when we take long rides! It's been so great that I just purchased another one for my second child yesterday :-)
