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.

STOP dangling legs in the car.
More comfort and safety while driving with supported legs.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.

Bringing a 1976 MG Midget to the modern world!
Material Type: 157mil Closed Cell Foam, Style: 157 mil 36 SqFt
I've been restoring a 1976 MG Midget barn find. I bought some Sinless liner to help make the car rattle less and feel more solid. This product is easy to cut, easy to install, and extremely sticky. I used it to line the trunk, the interior, and even some under the hood of the old MG. The adhesive stands up to the brutal temperature of the engine bay, and when (by accident) some fuel spilled onto the foam, it didn't fall apart or turn to mush. Thanks to Siless, the MG now feels like a modern car. The floor pans feel much more solid, the doors make a heftier thud when you close them, and the trunk no longer sounds like a percussion instrument when you touch it. If you know what you're doing, this product will transform the feel of a car. I found that 36 sq ft was enough for my MG Midget, but for a bigger car I would want more. The pattern on the back helped me to cut perfectly measured squares and rectangles. The foam itself doesn't have a strong odor, it works super well, and has held up to several months of changing temperatures (in the Midwest US.)
