Price Comparison
When it comes to pricing, the Evenflo Symphony Sport All-in-One Convertible Car Seat is the more economical choice at $189.99 compared to the Evenflo REO by Revolve360 Rotational Convertible Car Seat priced at $239.99. This makes the Symphony Sport about 17% cheaper. The price difference may be significant for budget-conscious parents looking for a reliable car seat. Both car seats are from the same brand, Evenflo, which is known for quality and safety in child car seats, but the Symphony Sport offers a lower entry point.
Modes of Use
The Evenflo Symphony Sport offers three modes in one seat, accommodating children from 5 to 100 pounds, while the Evenflo REO is designed primarily for rear-facing mode for infants weighing 4 to 40 pounds and forward-facing mode for children weighing 30 to 40 pounds. This means that Symphony Sport can serve your child for a longer duration as they grow. The versatility of the Symphony Sport makes it a better long-term investment if you plan to use the car seat through several stages of your child’s development.
Installation Ease
Both car seats emphasize easy installation, but the Evenflo REO stands out with its one-and-done LATCH installation system. This feature simplifies the installation process, allowing caregivers to install the seat securely with hassle-free hooks. In contrast, while the Symphony Sport has a no-rethread harness, which aids in adjusting the fit as the child grows, it does not offer the same one-time installation convenience. For those who prioritize a straightforward installation process, the REO may be the better choice.
Size and Space Efficiency
The Evenflo REO is designed with a compact 17-inch wide footprint, making it a great option for families with smaller vehicles or those who need to maximize backseat space for additional passengers. The Symphony Sport does not specify its width but is generally bulkier due to its all-in-one functionality. If saving space in your vehicle is a priority, the REO is the more practical option for tight spaces without sacrificing your child's safety or comfort.
Safety Features
Both car seats meet or exceed all applicable Federal Safety Standards, ensuring that your child is protected while traveling. The Evenflo REO includes robust safety features such as structural integrity testing and rollover testing, while the Symphony Sport also emphasizes safety, stating it goes above and beyond government standards. Parents can feel confident in either option, but the REO’s innovative design and extensive testing might appeal more to those who prioritize cutting-edge safety features.
Comfort and Convenience
In terms of comfort, the Evenflo REO includes an 11-position headrest that can be adjusted with one hand, along with a no-rethread harness for easy fitting. It also features removable, dishwasher-safe cup holders for added convenience. The Symphony Sport also boasts an adjustable headrest, but its Infinite Slide Harness does not require uninstalling the car seat to adjust. Both seats are designed for comfort, but the REO offers additional features that cater to ease of use and cleaning, which may be a deciding factor for busy parents.
Target Audience
The Evenflo REO is particularly aimed at new parents, grandparents, and caregivers looking for a secondary seat due to its compact design and ease of use. On the other hand, the Symphony Sport is designed for families who want a versatile car seat that can accommodate a wide range of weights and ages from birth to booster. Depending on your specific needs—whether it's a secondary seat or a primary all-in-one solution—one product may resonate more than the other.
Which should you buy?
Ultimately, the decision between the Evenflo REO by Revolve360 Rotational Convertible Car Seat and the Evenflo Symphony Sport All-in-One Convertible Car Seat boils down to your specific needs. If you prioritize a budget-friendly option with extended use and versatility, the Symphony Sport is the way to go. However, if you seek ease of installation, space efficiency, and innovative features like 360° rotation, the REO would be a worthy investment. Both seats are safe and reliable, making them excellent choices in the convertible car seat category.
