Overview
The Evenflo CS500312203 is priced at $119.99, which places it above many booster seats, but the 2,921 reviews at 4.5 stars reflect a broad base of satisfied buyers who have used it across varied vehicles and travel patterns. The standout specification is the dual installation option: both LATCH and seat belt are supported, which is not universal among booster seats and is a practical benefit for families who want the seat anchored in the car even on trips when no child is riding.
The seat weighs 9.6 pounds and measures 17 inches deep by 19 inches wide by 27.5 inches tall, fitting most rear bench positions. The polyurethane foam construction provides padding for comfort, and the 100-pound weight capacity extends usability well into the later childhood years. LATCH installation on a booster does not change how the vehicle's seatbelt works around the child, but it does keep the seat from tipping or shifting when unoccupied.
With 500 monthly purchases and a strong review base, the CS500312203 is a well-established product. Families who appreciate both the safety of LATCH anchoring and the strong community of existing reviews will find this booster a reliable choice at the mid-range price.
Pros
- 2,921 reviews at 4.5 stars is one of the strongest signals of satisfaction in this booster category
- Dual LATCH and seatbelt installation is uncommon in boosters and adds real convenience
- 100-pound weight capacity covers the child through many years of use
- Polyurethane foam padding provides ride comfort on longer trips
Cons
- At $119.99 it is priced higher than many competing booster seats with similar weight limits
- 9.6 pounds is moderately heavy if frequently moved between vehicles
- Seat-belt installation remains the core safety mechanism; LATCH anchors the seat but the seatbelt still protects the child

Performance notes
Booster seats that support LATCH allow parents to secure the seat to the vehicle's anchor points, which reduces the risk of the seat tipping over when the child is not in it. When the child is seated and buckled, the vehicle seatbelt routes through the belt guides and does the protective work in a crash. Owner reviews for the CS500312203 consistently mention comfort during extended car travel and the convenience of LATCH keep-in-place anchoring. The 27.5-inch height suggests meaningful back and head support typical of a high-back booster design.
What buyers say
With 2,921 reviews at 4.5 stars, buyer sentiment is very positive and the review volume gives that rating real credibility. Reviews at this scale tend to capture a wide range of use scenarios, vehicle types, and child sizes, making the 4.5-star average a reliable indicator of consistent performance. The 500 monthly purchase rate shows sustained ongoing demand, not just early hype.

Frequently asked questions
Does LATCH on a booster seat make it safer for the child during a crash?
LATCH on a booster seat primarily keeps the seat stable when no child is in it, which prevents it from becoming a projectile if it shifts in the vehicle. During a crash, the vehicle's seatbelt, routed through the booster's belt guides, does the protective work for the child. LATCH is a convenience and stability feature on boosters rather than a primary crash-protection mechanism.
How do I know when my child has outgrown the Evenflo CS500312203?
Your child has outgrown this seat when they reach 100 pounds or when the tops of their ears reach the top of the seat back, whichever comes first. At that point, if the vehicle's seatbelt fits correctly across their body without the booster, they are ready for the vehicle belt alone. If the seatbelt still does not fit correctly, a different booster style may be needed.
