The ELISEO booster seat complies with the latest and highest safety requirements in force and is approved according to the new R129 i-size standard.
Telescopic isofix connectors make it easier to install the seat. The colour indicators on the connectors allow verification of the correct installation.
The seat comes with 2 guides to assist clipping the Isofix connectors into the car.
ELISEO car seat can also be installed in vehicles not equipped with Isofix anchorage points as the connectors are retractable.


In all cases, the child is secured with the car’s 3-point seat belt on which the X-PAD is placed : a padded strap cover that guides the seatbelt comfortably over the child’s shoulder, absorbs shocks and can even be used as a small pillow!
For the good safety of the child, make sure that the two straps of the seat belt are not twisted, and pass them under the armrests. Check that the horizontal strap is correctly placed on the upper thighs (rather than on the belly) of the child.
ELISEO features an X-BUMP : it’s a removable extra side protection in two-component and honeycomb design. It should be mounted on the door side to stabilise the seat and absorb impact in the event of a side collision.


A magical trip starts with a comfortable car seat ! Thus, the outstanding comfort of ELISEO booster seat ensures children’s wellness while travelling and helps to inspire their imagination.
