So why is the Britax Companion so revolutionary? It is the first infant seat to address the issue of side impact safety. Sure, lots of infant seat have headrests and/or contoured support. In most cases, these do little or nothing in the event of a crash. With the Britax Companion Enhanced Side Impact Protection, you are assured of a safer, customized fit. Additionally, the rebound bar, absent on most infant seat models, helps minimizes the rebound trauma in an accident that frequently occurs in rear facing seats.

Please note: the Companion is slightly heavier than other infant car seats. However, the side impact protection more than makes up for the slight added weight
