This seat may look like an infant seat, and have the convenience of an infant seat – but the baby won’t outgrow it like an infant seat. Unlike most infant car seats which babies tend to outgrow around 6-9 months of age, this seat will accommodate virtually every baby until 12 months, and most kids until 18 months or older (baby must weigh less than 30 lbs and his head must be at least 1 inch below the top of the car seat).

This seat is perfect for parents who do a lot of traveling in vehicles besides their own – taxis, rental cars, airplanes, etc. Since this seat fits onto most snap n’ gos and stroller frames that accommodate infant car seats, it's a breeze to get your child and car seat to where you're going – just wheel them on the stroller (no need to carry the car seat and baby).

This is a convertible car seat (birth to 30lbs. rear-facing and 22-40lbs. forward facing). The car seat has a stroller built into it.

Please note the following complications associated with the Sit n' Stroll:

• Rear-facing: The Sit n’ Stroll typically sits too upright for infants without adequate head control. When used rear-facing it's often difficult to install securely enough (so that there's less than 1 inch of movement) as the seat is very wide (it's wider than the LATCH anchors in the vehicle’s seat crack).

• Forward-facing: Unlike other forward-facing car seats, where the belt (safety belt or LATCH) that secures the car seat to the vehicle is behind the child’s back or just alongside the car seat, the belt path on the Sit N’ Stroll is across the child’s upper chest. This difference means that the child must be secured in the car seat BEFORE you install the seat in the vehicle AND that the car seat must be uninstalled BEFORE you remove the child from the seat. This isn't a problem if you're going in a taxi or other vehicle that you use for one-way rides (and therefore will not be leaving the car seat in regardless). However, if you're renting/sharing a vehicle and using that same vehicle frequently throughout your trip, installing and uninstalling this car seat for every ride may become cumbersome.

Are you traveling in the US or Canada with a child who weighs more than 30 pounds? If so, then this extremely portable car seat is a great option. It installs quickly and easily, so when you get to grandma’s car or your rental car, you can be on the go in no time with your child extremely safe in a 5 point harness. It also comes with a convenient travel bag and weighs just 10 pounds.

This seat is not FAA approved (because it requires a tether or a shoulder belt, neither of which is found on an airplane), but will easily fit in an overhead bin on the plane. Your child will use the lap belt on the airplane just like an adult (note: the airplane seat belt fits much better than that in a vehicle).

Just remember – you MUST use the tether strap when using this in the car seat mode (kids 30-60 pounds). All Canadian vehicles have had tether anchors factory installed for many years, and factory installed tether anchors in US vehicles have been standard since model year 2000. Most countries outside the US do not have tether anchors in their vehicles – so in those situations you would use this seat as a booster if your child was more than 40 pounds (or a different seat if your child was less than 40 pounds).

These are appropriate for kids AT LEAST 40 pounds (and at least 3 years old). Many boosters have lower weight limits of 30 or 33 pounds – but it is strongly recommended that kids use a 5-point harness car seat until reaching 40 pounds.

There are many backless boosters for sale: Graco Turbo Booster, Evenflo Big Kid, Evenflo Right Fit, Cosco High Ride, Combi Everest, Britax Starriser.
