Britax Decathlon Convertible Car Seat

As an upgrade to the best selling Roundabout and Marathon car seats, the Britax Decathlon Convertible Car Seat adds new comfort features to the already impressive safety innovations of its predecessors. Far from being superfluous luxury, this comfort engineering helps to ensure that your child is always well positioned and protected in the Decathlon--which is quite an achievement considering the seat is rated to secure children from 5 pounds up to a whopping 65 pounds.

Included in the Decathlon's upgrades is a three-position crotch buckle that guarantees a continuously secure fit for your growing passenger. Also, the Decathlon features an infant positioning system with removable, washable body pillows to support a newborn, as well as a detachable, washable toddler pillow. As with all Britax car seats, the Decathlon includes a user-friendly push button release LATCH system and built-in vehicle belt lock-offs to make a tight installation quick and simple, whether you use LATCH or the vehicle seat belts. And, Britax's famous Versa-Tether allows both rear-facing and forward-facing tethering for maximum energy management and seat stabilization in the event of a crash.

With updated comfort features plus world renowned safety engineering, the Britax Decathlon Convertible Car Seat is the trusted choice of many parents.

Britax Decathlon Convertible Car Seat

The best-selling Roundabout and Marathon car seats have secured the Britax brand as a leader in the car seat industry. With the addition of the Decathlon to its already impressive product line, Britax offers a remarkable level of luxury to keep precious passengers both safe and comfortable. The Decathlon is a convertible car seat that can be installed facing rear for newborns and infants and then convert to a forward-facing seat to accommodate older babies. Like the Marathon, the Decathlon holds babies from 5 to 33 pounds in the rear-facing position, and in the forward-facing position the seat can support a remarkable 20 to 65 pounds and up to 49 inches tall, extending the seat's use well beyond most convertible car seats on the market.

Safety experts recommend the rear-facing car seat position at least until one year old and 20 pounds. Because the Britax Decathlon can safely seat most children in a rear-facing harness well past their first birthday, it's a great choice for parents of babies who have outgrown their infant rear-facing only seats but are still too young to move to a forward-facing seat. Or, if you want to avoid purchasing multiple seats, the Decathlon's higher weight limit makes it an excellent investment to comfortably accommodate most children from birth to age five.

The Britax engineers have made the Decathlon car seat a few pounds lighter than the Marathon, even though they share the same dimensions and most of the same safety features. The Decathlon's contoured base will easily fit in most vehicles, though in the rear-facing position it may be a snug fit in sports cars and others automobiles with small back seats. You'll want to allow 31 inches of back seat space to ensure a proper fit.

Like the Marathon, the Decathlon offers a tangle-free, five-point polyester harness with four harness heights. Unique to the Decathlon is a three-position crotch buckle - a great feature that will ensure your growing child has a snug and secure fit for years of use. The seat has a push-button front harness adjustment, as well as Britax's patented HUGS, or Harness Ultra Guard System, which gently cushions the neck and chest, reduces forward head movement, helps avoid improper chest clip placement, and distributes the harness load to avoid webbing edge irritation in the event of a collision. Another excellent safety feature is the patented Versa-Tether system, which anchors the top of the seat to the vehicle, reducing forward or backward movement in the event of a collision. While most car seats only provide tethering in the forward-facing position, Britax's intelligently designed Versa-Tether allows rear-facing as well as forward-facing tethering for maximum seat stabilization.

The Decathlon can be easily installed using lap belt and shoulder belt harnesses as well as the LATCH (Lower Anchors and Tethers for CHildren) anchoring system that accompanies most vehicles made after 2003 and a few models made in 2000 to 2002. The seat's premium, push-button LATCH connectors ensure a quick, simple, and tight installation every time. If you do not have LATCH or if you'll be using the car seat in an older model automobile with metal locking clips on the safety belts, the Decathlon includes built-in lock-offs to tightly secure the vehicle's seat belt in both the rear and forward-facing positions. For children weighing more than 48 pounds, be sure to use the vehicle's seat belts, not LATCH, unless otherwise specified by the vehicle manufacturer. The Decathlon conforms to all applicable Federal Motor Vehicle Safety standards and is certified for use in aircraft, meaning you can secure the Decathlon into an aircraft seat to keep your baby snug and your hands and lap free. Of course, always check with your airline for any size requirements or other regulations regarding child seats.

If comfort and convenience are high on your list, the Britax Decathlon offers impressive features to keep your little one cozy and content, perfect for road trips to see grandma as well as quick jaunts to the store. The seat's plush microfiber cover is removable and washable. Premium comfort pads protect baby's delicate skin from coming into contact with the harness system, and the matching belly pad keeps the lower buckle from irritating or pinching baby's tummy. A new comfort feature on the Decathlon is the infant positioning system with removable, washable body pillows to support your newborn, as well as a detachable, washable toddler pillow. In addition to the removable pillows, the seat's high density comfort foam gently cushions the child, while the EPS protective foam liner manages and distributes energy around the child's head and torso. The seat includes rear- and forward-facing recline options and an easy-to-reach front recline adjustor handle. Especially convenient are the Velcro harness belt holders, which keep the harness to the side while placing the child in the car seat, making boarding less stressful on the parent and baby.

The Decathlon's updated comfort and convenience features plus the rock-solid design and extended weight limit make it a very popular choice of savvy parents. BabyEarth offers the Britax Decathlon convertible car seat in four different fabric options, including the gender-neutral Sahara and the pink and sassy Tiffany.
