The Britax Marathon Infant/Child Car Seat is an excellent choice for getting your family where they need to go safely and comfortably. SafeCell Impact Protection surrounds your child in safety and Complete Side Impact Protection shields your child in a protective shell designed to absorb crash forces and protect from debris. A 10-Position, Quick-Adjust Harness makes it easy to ensure the proper fit as your child grows.
- Base with SafeCell Technology features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
- Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
- Energy-Absorbing Versa-Tether features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
- Anti-rebound bar to limit child seat rotation in a crash when installed rear facing.
- Easy-Remove Cover allows easy cleaning without disassembling the harness or uninstalling the car seat
- Side Impact Protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body

Our daughter is quite tall, and we found her previous convertible car seat made it impossible for her to climb into our car on her own. It also meant her feet were constantly pushing on the back of the front seat. This seat fixes all of those problems, and the buckles are much easier to use! We love it!

Love it.. however the front of the base does move around when you pull strap to tighten (even when secured very tightly with luas clips). This happens with our diono too,so not sure if it's just how these 3 in 1's work. If you leave straps fixed, it's not an issue. Great seat though and Love the easy height adjustment. Love Britax quality!
