Gap filler is very sturdy, so i expect it will hold up well. Putting them 'on' is simple, set it around the seat belt stem and tuck it into the gap.
The material is a softer foam that will fill the gap without making it difficult to move the seat. Fabric texture is top notch.
Every crumb and hair and piece of dust sticks to these dang things and it is hard to clean off. They slip actually, you have to keep adjusting them.
