KneeGuardKids4 - Car Seat Footrest


The best travel companion for all children in high-back booster car seats.

KneeGuardKids4, the first fully adjustable crash tested footrest helps to maintain the correct sitting position of the child in every forward facing car seat without a support leg in place, whenever travelling by car, regardless of the distance. Footrest eliminates numbness in the child’s legs as they will no longer lean against the edges of the car seat which causes pressure under the knees. What’s important, KneeGuardKids, when supporting legs, makes the child's back rest against the seat and its head remains within the protected area.

It is easy to assemble and adjust to individual needs of a little passenger. Suitable for cars with and without ISOFIX. In both cases, the footrest is fixed equally securely. In the event of an accident, it does not move around the vehicle cabin, so it does not pose a threat to passengers. It is recommended for children who kick into the seat in front or experience sore legs and back. The new model of the KneeGuardKids4 footrest was singled out in the Concept & Innovation Baby Products Association (UK) and Kind+Jugend (DE) competition.

When children's legs are dangling, strong pressure under their knees and calves, as a result of disordered blood and lymph circulation, is causing discomfort, numbness, pins and needles sensation and also weights the knee joints. The footrest maintaining the correct position of the hips and back in the car seat, correct seatbelt routing and avoiding kicking the seat in front of them.

Child’s dangling legs cause not only discomfort but also lead to adverse effects, which may be dangerous when traveling by car. Lack of footrest will lead to disordered blood and lymph circulation resulting in numbness and pain in the legs. Kicking into the back of the seat in front is the symptom that child feels discomfort and looks for opportunities to improve it. It is very important for the child’s safety to use the child car seat correctly. If the child does not sit in the correct position, even a slight collision or emergency braking may have serious consequences. The child’s limbs may suffer multiple injuries. Car seat will protect child effectively only if it maintains a correct sitting position in a car, like a crash test dummy.

Car seat footrest also helps avoid frequent, forced stops due to child’s discomfort both during long trips and short ones. The footrest is parents’ investment in the safety, health and comfort of children traveling in a forward-facing car seats. It is easy to assemble and adjust to individual needs of a little passenger. 

KneeGuardKids footrest can be firmly and easily attached in both vehicles with and without the ISOFIX system. The footrest maintaining the correct position of the hips and back in the car seat, correct seatbelt routing, avoiding, kicking the seat in front of them, resting their feet against the dri- ver's or passenger's seat, escaping or even submarining under the seat belt. KneeGuardKids has received positive feedback both from parents and experts in Poland, Germany, Spain, UK and USA.

KneeGuardKids4 - Car Seat Footrest


ISOFIX or Seatbelt

ISOFIX and seat belts are two vital elements when it comes to children's car seats. Both keep the car seat secure.

In terms of safety during impact, there is no difference between ISOFIX and belt attachment, as long as they are both installed correctly - they are as safe as each other.

Weight limit or height limit first?

Car seats that have a weight limit and a height limit are outgrown as soon as your child meets one of those limits. e.g. an infant carrier might have a 13kg weight limit and an 86cm height limit, the seat would be outgrown as soon as the child was 86cm even if they were only 11kg.

What is the Swedish Plus Test?

The Swedish Plus Test is the toughest crash test in the world! The Plus Test is a voluntary additional crash test that car seat manufacturers can apply for. Plus tested car seats ensure that your child is not exposed to life-threatening neck forces during a collision. Find out more about the Swedish Plus Test here.
