The Britax Roundabout scored 74 points out of 100 in our review of convertible seats, which gave it a 5th place rank out of 12 products. With only four seats scoring higher, and a price that is lower than the majority of options we reviewed, it is easy to see how it won a Best Value award in our review. This seat earned nice scores for ease of installation. It also scored well in our metrics for comfort and quality as well as crash tests. We think parents will really like this seat and with the money they save over the other Britax car seats we reviewed they are unlikely to even miss the non-rethread adjustable height mechanism, which is the only real downside to the Roundabout.
REASONS TO BUY
Reasonable price
Easy to install
Lighter weight
REASONS TO AVOID
Rethread harness is harder to use than non-rethread
Update January 2018
The Roundabout has been discontinued and is not being replaced with anything similar. There are still some available for purchase until the stock runs out. However, Britax now has the Essentials line of products that includes a similarly priced convertible car seat called the Britax Allegiance which appears to be similar to the Roundabout but with the better non-rethread harness adjustment we like. This may be a good choice for parents considering the budget-friendly Roundabout who aren't able to find it. Expect to see more on this new car seat in the future as BabyGearLab completes a review and crash testing.
Our Analysis and Test Results
The Britax Roundabout is the only brand of seat that has the "SafeCell" impact protection, with an integrated system of safety components that include a V-shaped tether with 2 strap design to minimize seat rotation, and staged release stitches that slow and reduce forward movement during a crash. The Roundabout installs using on/off lower anchors that lock in place with a click and release with a button push. The seat works rear facing for children from 5-40 pounds and up to 46 inches tall and forward facing for children 20-55 pounds and up to 46 inches. For comfort, the seat has three recline positions, plush foam padding and fabric, and a removable body pillow for smaller children. The Roundabout also features a two-position buckle strap and is engineered, tested, and made in the USA with global components.

Performance Comparison
This comparison chart shows the overall scores for each seat tested in this review. The Britax Roundabout is shown in blue. It is easy to see why the Roundabout earned a Best Value award compared to the scores and prices of the competition.
The following provides additional details on how the Roundabout performed during testing for each metric. Metric scores were used to calculate the overall score for each seat.

Crash Test
The Britax Roundabout has crash test data that are relatively impressive for the group of seats we tested. Sled crash testing data was taken from sensors placed in the head and chest regions of the crash test dummies used to record the amount of G forces that impact the body during a simulated crash designed to the same specifications as those used by the National Highway Traffic Safety Administration (NHTSA) in their testing.
All of the seat on the market in the US meet or exceed the Federal Minimum safety guidelines outlined in the FMVSS 213, and should, therefore, be considered safe; some seats seem to offer an additional margin of protection as indicated by their better than average sensor results. The Roundabout has G force data for the head sensor that is lower than 7 other seats we looked at, and chest sensor data that is lower than 4 of the competition in this review.
The charts shown below include the crash test data from the head and chest sensors for the Roundabout (shown in black). They also include crash test data for the products that had the least amount of G forces recorded for each sensor (shown in green) for comparison purposes.

Ease of Install - LATCH
The Roundabout scored well in the ease of installation for LATCH system with a 9 of 10.
Installation of the Roundabout is quite similar to the Britax Marathon. The LATCH anchors seem perfectly placed without the need for assistance from us. Installation is simpler than that with the vehicle belt because you won't need to thread the belt or take apart the seat to find the belt path. We found it is easiest to attach both side anchors with a lot of slack before tightening them both down. For forward-facing it is easiest if you tighten the tether first to avoid the strap getting caught behind the seat, but you'll still want ample slack in the LATCH strap to get both sides attached to the vehicle anchors. Loosening the LATCH strap is a little more difficult than tightening, but with any luck, you won't need to do this very often. It also isn't as difficult as some of the competition, so it is hard to get too upset by this feature.
The recline adjustment handle on the Roundabout is hard to use when the seat is installed rear facing, which is when you will need it.

Using the recline adjustment handle is easy in and of itself, but after the seat is installed rear-facing (which is when you will need the recline adjustment handle) you won't be able to reach the handle. So we recommend you make the change before installation or at least before you tighten the straps and secure the seat to the vehicle. To determine if you have the correct recline for installation, you will need to ensure that the line on the seat side is parallel to the ground. While not that difficult to manage, we prefer the bubble or ball style level over the line.
The Roundabout is one of the easiest in the group to install

Ease of Install - Belt
Installation of the Roundabout using the vehicle belt is almost as easy as with the LATCH. It earned an 8 of 10 for this metric which is 1 point below the high score of 10 earned by the Britax Boulevard ClickTight and the Britax Advocate ClickTight.
The low for this metric is a 5 earned by the Safety 1st. This seat proved difficult to install tightly no matter what configuration we used.
The rear facing installation on the Roundabout is easy enough to thread even though you will need to lift the seat bottom to manage it
The belt path on the Roundabout is under the seat padding and has two belt lock offs to keep it secure

The 2 part belt lock off on the Britax Roundabout required a screwdriver to pry open. It isn't as user friendly as some of the competition, but having a hard to use lock off is still better than not having one.

The worst part about installing this seat with the vehicle belt is the belt routing path. The pathway is hidden under the seat whether you are installing it forward or rear facing. This means you have to sort of take the seat apart to thread the belt. It will feel like the seat is dismantled before you find the pathway. The belt lock-off is also a challenge and requires the use of a screwdriver to get it open. This is neither convenient nor the best lock-off in the group, and we think possibly a little dangerous given that the screwdriver is sharp and one wrong move and it could cut your hand or damage the seat. Once you have the belt threaded, however, it is a piece of cake to pull the belt tight and close the lock off. This seat felt very secure no matter what car we tested it in, or what direction it was facing.
The Roundabout buckle is difficult to use compared to the competition, but it isn't the hardest one in the group

Ease of Use
The Roundabout is not a stand out for ease of use. Perhaps in part due to its rethreading harness height adjustment process. The seats that earned high marks for ease of use, for the most part, included a non-rethread harness adjustment.
The high for ease of use is 8 for the Britax Boulevard ClickTight and the Britax Advocate ClickTight.
The harness retention attachment points on the Roundabout don't work well and it is difficult to get the straps even to meet the attachment points

The buckle on this Britax isn't the best, but it is identical with the Britax Marathon and on par with much of the competition. The chest clip is one of the easier in the group and doesn't hurt your hands to use.

The Britax Marathon has an easy to use non-rethread harness height adjustment. Unfortunately, it's little brother the Roundabout does not. However, the threading of the harness is not difficult to use, just time consuming and it requires removing the child from the seat to accomplish it. It has four shoulder height adjustment positions and one rear facing crotch position and two forward facing positions. Both straps hook on the same splitter plate, which makes it a little more difficult than those that have separate hooks, but it still isn't a challenge. The slots for threading are large and are clearly defined by the cover. The tightening strap is located at the foot of the seat and is easy to use. Loosening is a hidden lever under the fabric cover near the foot of the seat. The lever is easy to use, and one of the few you lift instead of push.
The LATCH storage on the Roundabout is on the base in the back and they click in to stay in place

The Roundabout LATCH storage is easy enough to use with anchor points on the back of the seat for storage and bands to tie up the excess straps. The tether hooks on the back as well, and the excess strap is stored in a fabric pocket on the backside. They may or may not keep the straps out of the way. The user manual is stored behind the seat back padding in front of the belt path for the vehicle belt installation. This is probably not the best location as the book cannot be accessed with the baby in the seat and could become damaged by spills and other accidents.
The fabric on the seat wraps around the shell with elastic and is relatively easy to remove because it doesn't have a headrest to get in the way. You will need to unthread the shoulder straps to remove it entirely from the seat. The cover is machine washable and lays flat to dry. We like the covers that can be machine washed. It may be something you never need, but if your child ever gets sick in the car or spills a milkshake, you'll be glad it is an option.
The Roundabout might have scored higher for quality and comfort if the fabric was seamlessly attached to the seat as opposed to wrapped around like a slip cover

Comfort/Quality
The Roundabout managed a relatively high score of 7 of 10 tying with the very similar Britax Marathon. The Chicco NextFit, the Britax Boulevard ClickTight, and the Britax Advocate ClickTight came in with 9s thanks to very thick padding with the best LATCH storage.
Fabric on the Roundabout is a bit rougher feeling than that on the Marathon, making it slightly less comfortable but still nicer than most of the competition. There are softer velvety strips in the head region of the seat, but these are sort of useless until your child gets fairly tall. The padding on the seat is really nice, and the same thickness as the Marathon.
The seat back on the Roundabout does have some nooks and crannies, but it isn't as busy and convoluted as some of the other products we tested

The Marathon and the Roundabout have a similar shell back with lots of grooves and cracks; the only difference is the lack of adjustable headrest making the Roundabout marginally easier to clean. The Britax Boulevard has a closed back that creates a sleeker look and can be wiped clean easily. The foam on this seat and the other Britax options is the Expanded Polypropylene (EPP), which is more environmentally friendly and doesn't off-gas. We prefer this type of foam over the more common Expanded Polystyrene (EPS) that is stiffer and more brittle, but more common is seats and in bike helmets.
The bottom of the Roundabout is not entirely smooth, but it doesn't have any protrusions that could damage the vehicle seat

The overall fit and finish are very nice on this Britax as it is on most Britax models. The fit of the fabric on the shell is fairly snug; it isn't as sleek looking as some of the others, but still very nice looking. The infant insert fits neatly in the bottom of the seat, and it doesn't look sloppy like many of the others that fold in on itself. The bottom of the Roundabout is not completely smooth, but there are no sharp corners or protruding edges that would damage the vehicle seat if left for a long time.
The Britax is one of the lighter seats in the group with a weight of about 16 pounds. However, it is 19 inches wide, which makes it wide enough that 3 seats across in a back seat might not be possible

Weight
The Roundabout is about 16 1/2 pounds, which puts it in the middle of the road for weight. The heaviest seat in the review is 38 pounds for the Clek Foonf in the rear-facing position.
The Roundabout is 19 inches wide with only three seats in the group measuring wider. The lightest and one of the narrowest in the group is the Evenflo Tribute at a little over 9 pounds and 17 inches. The widest seat in the review is the Maxi-Cosi Pria 70 at 21 inches wide. The weight and size of the Roundabout are better than average for the products we tested, and it scored well in this metric tying for the high score with the Britax Marathon.
