We bought this foldable sledge for our 20 month old son, because we were doing a set with backrest. Although the extra of folding was not the most important criterion but we are more than excited. First, for processing: The slide is made of lacquered wood and is handled properly. It is very stable, despite the folding mechanism. The backrest have to assemble themselves, but is very easy - even for women. Bolts and everything else is. The folding mechanism: The whole thing is made from sturdy, hard plastic, only the lever for folding is made of metal. The flaps have been out to try again. Whether the lever rusts quickly, remains to be seen. When folded, the slide fits in even the smallest car boot. We have a small Polo and because it fits loosely inside. So even if you have to drive a little for sledding, with this slide no longer an issue. Also suitable for small cellar or storage rooms, as it hardly takes up space so. As I said, it's a sled to go. Overall, I'm very excited because I can firmly make a foot muff it. I can really recommend this slide, because it is water stable and foldable. Even if you go on winter holiday, this carriage can ride loose. Just buy it from me.
