Technical characteristics of the Britax Römer Evolva 123

The Britax Römer Evolva 123 model is a seat from the Seats and benches category, designed as a group 1/2/3 child seat with a booster function. The construction is intended to work across a wide range of child weights, which allows one seat to be used through several stages of development – from a toddler to an older child using the booster and backrest.

The presence of Isofix mounts enables a stable connection between the seat and the vehicle body, which improves the rigidity of the attachment compared to traditional mounting using only the seat belt. This type of solution limits unwanted lateral and longitudinal movement of the seat while driving, which is important for both the safety and comfort of the child.

Application and function in the vehicle

The Britax Römer Evolva 123 acts as a dedicated child seat that integrates with the vehicle's factory seat belts. The booster design with a backrest allows for proper belt routing over the child's shoulder and pelvis, which is crucial for the correct operation of the restraint system during daily use.

The 9–36 kg weight range means that the seat can be used in various child seating configurations, in accordance with applicable regulations and the seat manufacturer's recommendations. This makes it possible to gradually adjust the way it is used to the current height and body weight, without the need for frequent seat replacement.

Condition, origin, and identification parameters

The offered seat is in the category of pre-owned interior equipment, which allows for optimizing the cost of cabin modernization while maintaining product functionality. This item is assigned to the brand specified as Unbranded, while the seat manufacturer is indicated in the title, which makes it easier to match the user's expectations regarding a specific seat model.

To facilitate identification in catalog systems, the product has assigned designations such as SKU, OEM part number, interchangeable numbers, and MPN, which are visible in the technical specifications section and can be used for comparison with components already in your possession or vehicle documentation.

Benefits of installing a pre-owned Britax Römer Evolva 123

Using the Britax Römer Evolva 123 with Isofix mounts allows for organizing the seating area in the vehicle and adapting it for transporting a child across a wide weight range. The user gains the ability to use a single seat for a longer period, which reduces the number of subsequent purchases and simplifies interior configuration.

Choosing a pre-owned seat from this weight group can be particularly interesting for those who plan to build a more comfortable and functional vehicle interior while maintaining a reasonable budget.
