FAQs About Booster Car Seats

Click on the questions below to reveal the answers:

A booster seat is designed for children who have outgrown their high-back harnessed car seats, typically measuring 100 cm to 150 cm in height. It positions the vehicle’s seat-belt correctly and elevates the child for safe travel. My Babiie sells high-back booster seats and backless booster seats (suitable from 125cm-150cm)

Yes — our range of booster seats from 100-150 cm are built to the R129 i-Size standard, providing advanced side-impact protection and secure installation methods.

Depending on model, installation may use ISOFIX connectors and/or the car’s seat belt. Our manuals and support help ensure a correct, secure fit every time.

Our booster seats are designed to cover the 100 cm to 150 cm height range, which typically spans children from approx. 3.5 years up to around 12 years. Choosing this range gives you long-term value.

Yes — we offer spare covers and accessories so your booster seat remains fresh and fully functional.

Switch to a booster seat once your child has outgrown their high-back or harnessed car seat and is entering the height range of around 100 cm. Our My Babiie booster seats cover 100–150 cm.

While not always mandatory, ISOFIX installation adds an extra layer of safety and simplifies correct fitting. Many My Babiie booster seats include ISOFIX connectors or provide both ISOFIX and belt-fit options.

Check your vehicle’s manual for ISOFIX anchor points and seat belt compatibility. At My Babiie we also provide sizing guidance and installation videos/manuals to ensure your 100–150 cm booster seat fits your vehicle correctly.
