125cm Harnessed Car Seats

Extended safety, comfort, and peace of mind.

Our 125cm harnessed car seats are designed to keep your child safely harnessed for longer — typically all the way up to around 6 or 7 years old, depending on their height. These seats go beyond the legal minimums, offering extended harness use up to 125cm, which can provide added protection in the event of a collision.

At Car Seats Plus, we only stock harnessed seats that we trust — many of which are Swedish Plus Tested or allow for Extended Rear Facing. Whether you’re looking for a seat that offers flexibility between rear and forward facing, or you want to keep your child harnessed as long as possible before transitioning to a high back booster, you’ll find trusted brands and expert-approved options here.
