Is it safe for my child to sit in a reclined position in their booster seat?

Always ensure that the vehicle seat is locked in the upright position. Never allow the child to sit in a booster seat with the vehicle seat back reclined.

You can safely recline the Oobr booster seat when used in full back mode, providing it is installed using the UAS connectors and that the child is properly positioned and securely fastened in the booster seat. Always check that the vehicle seat belt fit on the child whenever the recline position of the booster seat changes.

It is NOT safe to recline the booster seat if it is installed without using the UAS connectors.
