Knee Guard Kids 4 is the first fully adjustable, crash-tested footrest that helps maintain the correct seating position of a child in any forward-facing car seat without a support leg while traveling by car, regardless of distance. The footrest eliminates numbness in the child's legs as they no longer lean against the edges of the car seat, which causes pressure under the knees. Knee Guard Kids ensures that when supporting the legs, the child's back is against the seat and their head remains in the protected area. It is easy to assemble and can be adjusted to meet the individual needs of a young passenger. In the event of an accident, it does not move within the vehicle cabin, thus posing no danger to the occupants. It is recommended for children who kick the front of the seat or experience pain in their legs and back. The Knee Guard Kids 4 is quick to install. The installation and use of the Knee Guard 4 are designed to be child-friendly and user-friendly. Carabiners keep the footrest securely attached to the Isofix, and the weight of the seat, along with fastening clips, ensures a stable position. It can also be mounted on Isofix seats. To simplify getting in and out, the footrest can be folded up and down. This allows your children to easily and independently get in and out without difficulty. With a large height adjustment (54 cm) and angle adjustment (135 degrees), the footrest is suitable for children up to 9-10 years old.
