Britax Roundabout Convertible Car Seat Onyx

Travel safely with your child when you use this car seat that is designed with safety and comfort in mind. Featuring two position set ups, it can hold up to 40 pounds.
Britax International has been manufacturing innovative, industry-leading child products for over three decades. Their dedication to safety, comfort, and convenience is certainly apparent in this convertible car seat. The Roundabout has enough features for baby and parents to run rings around the competition.

Safety first is a good rule of thumb, and one that Britax certainly heeds. The Roundabout offers features you might find on many other car seats, such as convertibility, a five-point harness, and the LATCH system. But Britax enhanced and then went above and beyond the norm when creating the functional and fashionable Roundabout.

Harness adjustment
One-pull harness strap adjuster makes for a quick, easy, and snug fit every time.
Their five-point harness system is made with strong polyester webbing, fits snugly over baby's shoulders, collarbone and hips to provide a secure fit, and the straps are designed to remain tangle free. There are also three adjustable shoulder height positions so the car seat grows with baby. A patented "floating" HUGS (Harness Ultra Guard) system better distributes the webbing loads, reducing head movement and minimizing harness irritation on baby's neck in case of an impact. HUGS also reduces the chance of improperly positioning the chest clip.

Located near a vehicle's seatbelts, factory installed anchor points provide a secure and easy LATCH connection. In conjunction with this push-button release system, the Roundabout also offers Britax's Versa-Tether®, an anchor aid that works both rear- and forward-facing and prevents the seat from tilting in the event of an impact.

Need more? The Roundabout provides built-in lock-off clips that keep the seat tightly in place when using only traditional seatbelts at installation. A simple handle pull allows the car seat base to be easily reclined when rear-facing. The one-pull harness strap adjuster makes for a quick, easy, and snug fit every time. A comfy ride is guaranteed for baby through the special EPS impact foam padding and soft fabric cover, which is removable and washable. The Roundabout is Federal Motor Vehicle Safety Standard (FMVSS) 213 compliant, making it approved for use on airplanes as well.

recline feature
A simple handle pull allows the car seat base to be reclined when rear-facing.
The Roundabout's versatile, contoured base means it will easily fit in almost every car, and can be positioned correctly every time, regardless of whether your vehicle is LATCH compatible or not. The car seat measures 18.25"W x 25"H x 23.5"D and weighs just less than 14 pounds when empty. Since car seats are mandated by law, it's nice to know that Britax is at least making the decision simple. The Roundabout is easy to install, super comfortable for baby, available in a range of colors and patterns, and, most importantly, safe!

Comparing Britax Car Seats
If you're debating between the Britax Roundabout and the Britax Marathon, think of the latter as the big brother. They are identical in comfort and convenience features, but the Marathon has a higher weight maximum and is larger than the Roundabout.
