Comfort, safety, and extended use, together in perfect harmony...

Designed for use from birth to booster, the Evenflo® Symphony™ All-In-One Car Seat delivers a refreshing combination of extended use design, riding comfort, safety and fit—all at a great value. Stretch the leading-edge safety through the toddler years, by using the 5-point harness up until your child weighs 65 lb. Keep your child comfy from one stage to the next, with FreeFlow cooling mesh that keeps them dry and comfortable in their seat. For on-the-go conveniences, you’ll appreciate the dual, built-in cup holders, removable head and body pillows, plus a seat pad you can toss in the wash for easy cleaning. From safety to comfort and convenience, the Symphony is music to parents’ ears on every level. 

At Evenflo, we go above and beyond government standards to create car seats that are safe. The Symphony All-In-One Car Seat meets or exceeds all applicable federal safety standards and is temperature tested and structural integrity tested at energy levels approximately 2x the federal crash test standard.  

It's been 100 years and Evenflo continues to push the boundaries in baby and children’s gear design and innovation. We meet the needs of new generations of parents by focusing on what they really care about: leading-edge safety, smart design and technology, and convenient features that help them enjoy the journey of parenthood.
