The Growing booster seat is compact and portable, allowing you to take it anywhere. It is made from a sturdy plastic inner frame and covered with polyester. The 3-point safety harness ensures a secure hold for your children. It is universally applicable to all common chairs with a backrest. Place the booster seat flush against the chair back and securely attach the upper strap to the chair back. Now tighten the shoulder straps and the seat area. Check the firm hold of the booster seat on the chair, also ensuring that the chair itself is stable. It features a large inner pocket and side pockets with zippers, so you can also use it as an organizer.
