Ease-of-Use

The Britax 70 G3 can be installed quickly and easily. The height of the harness can be adjusted without having to re-thread it each time. The thick harness straps do not tangle easily and there is a crotch strap that is long and has two positions so that it is easy for larger children to be secured. The seat can be installed with a push button latch connector which does not require much digging in between seats to fasten the belt. Lock-off fasteners help to keep the belt tight around the seat when latch connectors are engaged. The seat cover can be removed without having to uninstall the seat and it is durable enough to be washed repeatedly.

Comfort

The Britax Marathon 70 convertible car seat is deep and has plenty of room. It has a nice plush feel and there are protective side wings which provide a good resting point to support the heads of sleeping children. There are many reclining positions that the seat can be placed in whether front or rear facing so that the child will be comfortable.

Safety

The Britax 70 G3 is safe for children from five pounds to forty pounds in the rear facing position. It should then be turned to a forward facing position and can be used for children right up until they are seventy pounds. The height limit for the seat is 49 inches but the shell of the seat is short so taller children will not be able to continue using the seat once their head is higher than the back of the seat. There is a base with cells that are designed to compress in the event you are involved in a collision. This works to lower the center of gravity of the child and reduce their forward thrust. There are integrated steel bars which will help to strengthen the connection to the vehicle and lower the amount of forward flexing in the car seat. This also helps to keep the seat stable.

The sides of the seat are deep and rigid and will absorb the energy with foam to provide protection from side impact to the child’s head and their chest. The tethers absorb energy and help to keep the car seat stable from the top in the forward facing position and also the rear facing position. There is a five point harness that has chest pads to keep the top of the harness in place on the chest of the child to provide the ultimate in protection during a crash. The Britax Marathon height limit is reached when the child’s head is an inch below the rear of the back of the seat. For most people the Britax Marathon review provides enough information for them to make an informed decision regarding the seat.

Quality/Durability

Many review is a good one because this company offers a Britax Marathon 70 manual that provides comprehensive installation instructions for this model and several others. You will need to know the date of manufacture if you misplace your manual so that you can locate the right one. Every Britax car sea offers a one year limited warranty. The seat will expire after seven years, so once that expiry date has passed, the seat should no longer be used. The seat should also be replaced after it has experienced a moderate or severe crash. There are specific criteria listed on the website if you are not sure what type of crash will make it necessary for you to dispose of the seat.

Material and Colors

The Britax Marathon car seat is manufactured from durable materials that are designed to last as long as the car seat. There are several colors available for this seat including Azalea and Grey, Chili Pepper and Black, Cowmooflage and Black and White, Jetset (grey, red and black), Onyx (black, white and grey), Wave (grey and dark grey), Waverly (Brown & black).

PROS

The seat suits most needs of children and parents, in that it can be used from infant right into toddler stages. It is roomy and comfortable and a cup holder accessory can be purchased for the seat. When you start to look around you may notice that it is difficult to find a bad Britax Marathon 70-G3 review.

CONS

This seat may be difficult to fit into a smaller car, but most car seats are. The chest pads on the straps can be difficult to use on small babies. Taller children may need to ride in a forward facing position sooner than most parents would like them to.

BOTTOM LINE

Britax Marathon 70 G3 has an impressive ease of use reputation amongst parents as well as experts. The steel-reinforced frame and the tethers have earned praise and make this seat among one of the safest available. Many parents love the fact that the seat is simple to install and just as simple to adjust. It provides an ultimately comfortable ride most babies and toddlers.
