Both small cars’ seats were designed with enhanced safety in mind, they just have slightly different features that make up the safety of the child’s car seat. It has two layers of side impact protection built into the car seat. The base was also designed to absorb energy using the Safecell Impact Protection. This means that if there were ever a car accident, the impact-absorbing base is meant to absorb the energy that is produced by the impact. Furthermore, you can clasp cup holders on it.

The main safety feature of this brand is SafeCell Technology. This piece of technology can compress and lower the center of gravity of the car seat. In other words, if an accident happened, SafeCell Technology would kick in and the car seat would be less likely to have forward movement. It also has side-impact protection, a steel frame, and energy-absorbing shell foam surrounding your child’s neck and body for neck protection.

One feature that these two car seats have in common is the Marathon  ClickTight and the Boulevard  ClickTight. This is an added feature that provides maximum safety to your child. When you install the car seat, lift open the front and feed the seat belt through, then shut the car seat. When the car seat is shut the Marathon ClickTight and the ClickTight convertible car seat installation system features automatically lock the seatbelt and automatic level indicator, leaving no room for the car seat to wiggle around.

Weight Limits

In the weight limit category, ClickTight Models are the same. In the rear-facing comfortable position, your child’s comfort when sitting is important, even while they weigh between 5 and 40 pounds. The front-facing position will hold your child between the weights of 20 and 65.
