1. Release the booster chair attachment system by pressing the two-stage lock (a black knob on the back of the booster chair). The attachment strap is now unlocked and you can feed it out to the required length.
2. Place the BABYBJÖRN Booster Chair on an appropriate* chair and secure the attachment system by fastening the clasp and then pressing-and-twisting the black knob to tighten the straps.
3. Make sure that the straps are properly tightened – they should not hang loose under the chair. Always check that the booster chair is firmly and securely fastened on the chair before letting a child sit on it.
Remember! Use the attachment system at all times!
*The BABYBJÖRN Booster Chair fits most chairs. For safety reasons, use only on chairs with four legs and a backrest. Not for use on bar stools, stools, folding chairs or chairs with a round seat.
