Review of the Evenflo Symphony 65 DLX All-In-One Convertible Car Seat


There are so many convertible car seats on the market and it is hard figuring out the right one to purchase.  A few months ago, I had the pleasure of working with Evenflo to review their Symphony 65 DLX (previously known as the 65 e3) All-In-One Convertible Car Seat. I was not in the market for a car seat but I am happy that I have the opportunity to share this highly rated car seat with our readers and my daughter was excited to have a new car seat. In operation for 85 years, Evenflo has been a worldwide leader in the development of innovative infant equipment and is now one of the nation’s leading manufacturers of high quality baby care and juvenile products.

  • SureLATCH Connectors Just Click, Click, Push for super-fast, super-snug installation in less than 60 seconds!
  • e3 Side Impact Protection significantly reduces the forces in side impact crashes through advanced energy absorption and an expanded zone of protection.
  • All-In-One Car Seat – The only car seat you will ever need from infancy (5 lbs minimum rear facing) to 65 lbs (forward facing) and to 110 lbs as a booster seat
  • Infinite Slide™ Harness easily slides for an accurate fit every time. No reworking the harness as child grows!
  • Up-front multi-position recline for child’s comfort while asleep or awake
  • Removable head and body pillow for additional comfort and support
  • One-hand adjustable headrest grows with your child
  • Fold-down cup holder for easy access to drinks and folds out of the way when not in use
  • Easy-off, machine-washable car seat pad requires no harness rethreading
  • Energy absorbing foam liner provides added safety & comfort

  • Certified For Use In Aircraft: ONLY when used with the 5-point harness this restraint meets FAA Inversion requirements for airplane use.
  • 6 colors


  • Wide car seat – fine unless you need to fit 3 car seats in a row or need space for 3 passengers in the back
  • Harness straps can twist easily – it happened to us within a few days
  • Different loosening system – it does not loosen at the shoulders like most models, it actually loosens at the hips. It took me some reading to realize because all the other car seats I have encountered loosen at the shoulders.
  • Harness cannot be removed or replaced
  • SureLATCH isn’t a sure thing in all vehicles
  • No EPP foam behind the head for infants
  • No lock-off device for seatbelt installations
  • Not very tall in booster mode
  • $230 – expensive regular price

I set my husband to installing the car seat a few days after receiving the car seat. He found it easy to install and did it quickly without any issues. The no rethread harness is awesome…just makes it so much easier to allow my daughter to grow into the car seat. The deep seat is super comfortable for sitting and sleeping. My daughter is happy with the car seat and so am I!
