If you're looking for a convertible car seat that is back-friendly and grows with your child, the Baby Jogger City Turn and Cybex Sirona S are two of the only convertible car seats that rotate toward the car door to make it easier to help your child in and out.

Although both models are priced at $499 and offer similar benefits, differences in other features set each car seat apart.

The City Turn rotates 180 degrees in the rear-facing position but doesn't rotate when forward-facing. Among its features are an easy-to-follow installation method and moisture-wicking fabrics that add comfort for your child.

The Sirona S offers 360-degree rotation for both rear and forward-facing use, a high-tech chest clip with SensorSafe technology, and a feature not seen on any other U.S. convertible car seats: a load leg to minimize rebound motion in the event of a crash.

In this article, we'll review the features, specifications, and pros and cons of the Cybex Sirona S and Baby Jogger City Turn.

Baby Jogger City Turn

The City Turn by Baby Jogger is among the first convertible car seats in the U.S. to feature a rotating swivel base.

In rear-facing mode, the base allows a 180-degree turn that brings your child 10 inches closer to you, allowing parents to keep a more upright posture that makes it easier to get your child in and out of the vehicle. 

The integrated RAPIDLOCK belt-tensioning technology and push-button LATCH make for a simple and secure installation in seconds. A 10-position headrest and 5-position recline ensure a comfy ride, and the no-rethread harness means you can adjust the harness without removing it. The City Turn has been engineered and tested with TRUE Test Plus safety standards (Tested to Reality Under Extremes) to help protect your child in rollover, side, front, and rear collisions.

Premium padding, a removable infant insert, and buckle covers add comfort and support, while the soft, lightweight fabrics with COOLMAX moisture-wicking material will help keep your child cool and comfortable from day one.

Cybex Sirona S

With its 360-degree rotation, you can rotate the Cybex Sirona S toward the car door to help your child in and out of their seat. You may only need to install it a single time using the vehicle seatbelt and EasyLock system because the seat will rotate from rear facing to forward facing in one motion.

The Cybex Sirona S is also the only American convertible car seat with a load leg, a metal bar that extends from the base of the seat to the floor of your car to inhibit movement and prevent head injury.

Energy-absorbing pods that extend from the sides of the seat to absorb 25% more forces in a crash, while SensorSafe technology integrated into the chest clip sends safety alerts to both a vehicle receiver and a smartphone. The alerts notify parents to potentially dangerous situations, like a child being left in a car, an unbuckled chest clip, unsafe temperatures or a child seated for too long.

With features like a no-rethread harness, included cup holder and numerous recline positions, the Cybex Sirona S offers the ultimate in convenience and safety for your child from birth to 65 pounds.

 

Baby Jogger City Turn vs. Cybex Sirona S Price

The Baby Jogger City Turn and Cybex Sirona S have the same price point, regardless of color.
  • City Turn: $499.99
  • Sirona S: $499.95

Baby Jogger City Turn vs. Cybex Sirona S Height and Weight Limit

Both the Cybex Sirona S and Baby Jogger City Turn support your child from day one, starting as a rear-facing seat for a newborn and transitioning to a forward-facing seat for an older child. 

Besides a one-pound difference in the starting weight capacity for newborns, both car seats have the same rear-facing weight limit of 50 pounds, and both have the same 65-pound capacity once used forward-facing.

Either car seat will support your child until around the age 5 or 6, when they reach 49" in height or 65 pounds in weight, at which time they'll transition to a booster seat.

Rear-Facing

  • City Turn: 4 to 50 pounds; 49" or less
  • Sirona S: 5 to 50 pounds, 49" or less

Forward-Facing

  • City Turn: 22 to 65 pounds; 49" or less
  • Sirona S: 22 to 65 pounds, 49" or less

Weight Limits for Installation with LATCH

All convertible car seats must eventually be installed with the vehicle seatbelt as your child grows because the combined weight of the car seat and your child will exceed the weight limits of the vehicle LATCH system.

  • City Turn: 4-35 rear-facing; 22-40 pounds forward-facing
  • Sirona S: 5-30 pounds rear-facing; 22-35 pounds forward-facing

Baby Jogger City Turn vs. Cybex Sirona S Safety Features

The Baby Jogger City Turn helps ensure that the most important element to car seat safety—a correct installation—is easily achievable, thanks to clear and easy-to-follow installation instructions and color coded belt paths.

Baby Jogger has tested the City Turn to their TRUE Test Plus safety standards (Tested to Reality Under Extremes) to help protect your child in rollover, side, front, and rear collisions.

EPP foam in the City Turn shell is energy absorbing, while a steel-reinforced frame is strong and durable without being overly heavy.

Cybex builds in a number of innovative safety features to the Sirona S, including one that isn't found on any other convertible car seat—a load leg that's used both rear and forward-facing mode to minimize rebound motion in event of a collision.

Extendable side-impact pods absorb up to 25% more forces in a collision and EPS foam in the shell direct energy away from your baby.

Unique to Cybex car seats, SensorSafe 2.0 technology is integrated into chest clip, a system that communicates with your vehicle and an app on your phone to alert parents and caregivers to unsafe situations like temperature extremes, an unbuckled seat while driving, or buckled seat after the car is parked and locked.
