Choosing a Safety Car Seat

Safety car seats are mandatory for the reason of it being a proper way to secure children while they travel with the vehicle. There is no guarantee that even when parents are already driving safely, there will be zero risk of getting involved in an accident. The safety seat is meant to hold the children’s body or restraining it from the impact. The seat is usually shock absorbing too for reducing the amount of energy being transferred to the passenger when facing the impact.

When it comes to safety car seat, parents have to consider lots of factors but the basics is making sure the seat is coming with the standard based on the system applied in your country. The next factor is based on the weight. Car seats are made based on the weight range and parents have to use them since day one when travelling with the baby. The first seat you have to buy is a baby carrier or convertible car seat.

Baby carriers are very convenient because they are easy to mount to the car seat base or your stroller and usually sold with the stroller in a travel system. The usage is not very long because they are the smallest among car seats but for parents who often use the stroller, having an infant car seat will be very helpful. Convertible car seat is larger and probably the longest in terms of usage. Depending on the baby, we usually can secure them with the harness using insert or padding.

It is useful until the kid is ready to move into the booster seat and the name convertible car seat itself comes from the way it is installed facing rear or facing the front of the vehicle. In order to know when to move into the front installation, we can match the weight and height of the kid based on the seat weight and height limit. Booster seat is when the kid can wear a seatbelt so the seat is meant to improve the weight and depth of the passenger’s body.

Besides the type of seat, parents have to consider the installation of the seat itself because the car seat needs to be installed properly for it to be effective. The safety seat has to stick to the car seat using rear anchor, seatbelt, and tether depending on the installation mode. Some car seats are a breeze to install while some require more effort. Just because they are easy to secure on other car types doesn’t mean it will perform the same with our vehicle.

About Cybex Sirona S and Evenflo 360

There are so many good car seats to choose from based on which seems to fit in your lifestyle or preference the most. Usually the more expensive the seat is, the more features they can offer and they can be easy to work with, especially with the installation system. If parents don’t have much time to scroll the options one by one, it is easy to see what the other parents are going with since you may like their choice too.

If parents are willing to pay extra for the ease of use, Cybex and Evenflo are going to be two interesting brands to consider. These two are famous names in the market for children safety car seats and the reason is they do offer lots of features or upgrades on the product quality. They are more expensive however so it may not be as interesting compared to many other alternatives such as Graco Extend2Fit Vs TriRide. There are also plenty of seats that parents can consider from their collection.

Some of the most interesting options are Cybex Sirona S and Evenflo 360, especially if parents have a concern about installing and removing the children from their seat. Compared to many standard safety seats, these two are going to be different and unique because the seat itself is not fixed in one position. Being adjustable helps users to put their kid and secure them as well as removing them from the seat without having to lift them higher from the seat’s sidewall.

Based on the type, both Cybex Sirona S and Evenflo 360 are already quite different because while both can be categorized as a convertible seat, the Evenflo 360 is actually an all-in-one solution similar to the Graco Extend2Fit 3 in 1. This means the seat can be used as a booster seat too when they exceed the height range of its harness. Price wise it is also affordable for what the seat can offer and if you want to optimize the budget, we do recommend getting this variant.

Cybex Sirona S and Evenflo 360 Design

Before getting into what the safety car seats can offer, let’s take a look into the unit first. In general all car seats are very similar but these two are not very common. Unlike most seats with a base that is only at the bottom of the seat, these two have a flat panel that will face the backrest of the car seat when installed. With this type of design you can expect the seat to be reclined into several positions.

You may notice a leg on the Sirona S and wonder what it is used for. This panel is adjustable and meant to hold the extra weight or dimension of the seat so it becomes more stable despite the wide base. Typical convertible car seats are usually around 20 pounds but these two are about 30 pounds, probably for the base design. Material wise the two are mostly made of hard plastic for the casing and base while the padding and fabric cover itself are both soft and comfy.

Cybex Sirona S and Evenflo 360 Installation

Moving further, let’s see what the Cybex Sirona S and Evenflo 360 can offer starting from the installation system and the best part is that they are quite different from the common car seats we have seen. There is only one belt path here meaning the installation can only be done using a lower anchor or seatbelt. The reason why many parents want these seats is probably because it is an all-in-one installation, for as long as your kid fits in the seat.

We personally like the Evenflo seat better because you can separate the seat and the base for installation and while it is quite heavy, the system is more easy to use and secure this way. The Sirona M installation with its metal feet is a bit tricky because the height has to perfectly touch the vehicle’s floor and depending on your seat’s height or vehicle type, getting to this perfect height can be difficult without a weight pressing the seat down. The belt path of Sirona is also narrow.

Cybex Sirona S and Evenflo 360 Fit

Next for the fit of these seats, they are useful from day one but, since not every baby weighs and has the same exact height, it is wise to try it with your infant first. A 17 inches long baby should fit nicely with the inserts in both Cybex Sirona S and Evenflo 360 but the weight limit of Sirona M is higher for up to 50 pounds when in rear facing while Evenflo 360 is for up to 40 pounds only. The height limit is also different because Sirona is taller so the kid can stay longer in rear facing mode.

For parents who plan to use the rear anchor, do note that its weight limit is 35 pounds only for both seats so we recommend using the belt for convenience. We need to rotate the seat facing the front and change the recline to an ideal angle for the weight when the kid exceeds the rear’s weight or height limit. The forward facing of these seats are up to 65 pounds and around 49 inches tall or one inch before the kid’s ear reaches the top of the headrest.

Additionally, since Evenflo 360 is an all-in-one seat, we can transform it into a booster that can secure passengers up to 120 pounds and 57 inches tall. Depending on the child’s growth they may need this mode when reaching 6 or 7 years old while with Sirona M we should move to another seat.

Cybex Sirona S and Evenflo 360 Features

Lastly for the features, the most interesting function of Cybex Sirona S and Evenflo 360 is their rotating system. This way parents can install the seat with a seatbelt and leave it until changing into another seat or moving to booster mode with Evenflo 360. Taking the passenger out of their seat is also easier since parents can rotate the seat to the side. In addition, the basic features like two cup holders are still present on both seats.

Cybex Sirona S Vs Evenflo 360

The Cybex Sirona S and Evenflo 360 are convenient options if parents want a car seat that is both easy to use and operate. They are also coming with more features than what we can cover above but for the most important part like installation point, the Evenflo is more straightforward. The additional leg on Sirona M is meant for safety purposes but can be an extra hassle to deal with. Once installed properly they are good for years and even more since Evenflo 360 can be converted into booster seat.
