The BABYBJÖRN Booster Chair attachment system keeps it securely fastened to the chair. Part of this system is the two-stage lock that prevents children, or siblings, from releasing the booster chair when it is strapped to the chair.
In addition, the non-slip straps and mini pads underneath ensure that the booster chair remains firmly positioned on the chair, and the ribbed seat surface makes the seat less slippery.
Always check that the product is firmly and securely fastened on the chair before letting a child sit on it. The straps should be retracted and the clasp fastened when the product is not in use.
