## Description

EVOLVAFIX is designed to protect children from 15 months, right up to the age of 12 years. Approved to the new i-Size regulation, it offers safety you can trust, and maximum flexibility. The seat converts from a harnessed seat to a highback booster seat, with just a few simple steps. Children can benefit from 5-point harness protection up until they reach 105 cm (max. 22 kg).

Review: Great seat! - Initially, I bought a cheaper seat to save money. Mistake. You really do get what you pay for - this seat is easier to use and far more comfortable for my boy. Being Isofix, it clips in quickly and the anchor at the back is simple to use too. It has a lot of adjustment too, so it should last for quite a while as my boy gets bigger. It simply works, can't ask more than that. desertcart is asking about reclining - no, it doesn't recline.
Review: Highly recommended - I bought this car seat and it’s absolutely amazing! My 4-year-old daughter loves it — the fabric is super soft, the quality feels really high, and it was so easy to install (literally a 2-minute job). She can sleep comfortably during long journeys, and her head doesn’t bounce around because the seat sits at a nice slight angle. Honestly, I don’t know what else to say except that it’s just lovely!

### ⭐⭐⭐⭐⭐ Great seat!

### ⭐⭐⭐⭐⭐ High safety standard
*by G***Y on 19 November 2025*

Very good quality and meets a very high level of safety standard. Its not to heavy for moving from car to car and the grandson seems comfortable in it. The iso fix and top strap make it very secure
