About this item
Product details
The Evenflo EveryFit/All4One 3-in-1 Convertible Car Seat has been engineered for maximum comfort, safety, and longevity. This car seat accommodates your child by adjusting to multiple positions, allowing kids to ride rear-facing beyond 2 years of age — without extending the seat or cramping other passengers. This all-in-one car seat provides a safe and secure ride for up to a decade. Parents and grandparents love the Quick Connector LATCH and belt guides for an easy and tight installation. It can be used as a rear-facing car seat with harness, forward-facing car seat with harness and belt-positioning high-back booster that helps keep children 4 - 120 lb secure while riding in a vehicle.
The EveryFit/All4One 3-in-1 meets or exceeds all applicable federal safety standards and Evenflo’s side impact standard. It is designed and tested for structural integrity at energy levels approximately 2X the federal frontal crash test standard.
Evenflo works with parents to develop child-restraint products that are designed for how they are actually used. We’ve developed this 3-in-1 car seat with comfort, safety and ease-of-use in mind. The one-hand, 12-position headrest and no-rethread harness enable a proper fit during each ride and as child grows – without uninstalling the car seat. For additional convenience, this all-in-one car seat is designed with removable cushions, machine-washable fabrics, two integrated cup holders and removable snack tray.
Families have trusted Evenflo® for more than 100 years for smart, innovative gear designed to make life easier, safer and more comfortable at home and on the go. We believe every moment with your growing little one counts — that’s what drives us to find new ways to simplify the work of parenting and caretaking. With the time and peace of mind you need, you can focus on what matters most: your child.
