This product is holding up well after 3 years of use and is well worth the cost to protect our car seats. I've used it to cover three different seats (all various sizes and shapes and brands) and the seat always fits inside. Its also stood up to rough handling from the airlines with minimal damage (a little scuffing on the fabric). When not in use it doesn't fold perfectly flat, however, the seams are a bit stiff, as is the fabric - just a note if storage is an issue.
