ADVANSAFIX M i-SIZE 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 21 kg.
i-Size safety for all ages
The ADVANSAFIX M i-SIZE will protect your child from their toddler years all the way to when they no longer need a child car seat - giving them the ideal car seat safety in one combination seat that is approved to the new i-Size regulation. What's more, its 5-point harness can be used for longer as it's suitable for children up to 21 kg.
Flexibility at your fingertips
Thanks to the FLIP&GROW function, you can easily change from the integrated 5-point harness to the car’s 3-point seat belt as your child moves to the next stage. And because no parts have to be removed from the seat when changing stages, the seat can also be converted back at any time. With the EasyRecline function, you can recline the seat to your child's comfort without readjusting the installation.
