My son is 3 years old and he needed help the first 2-3 times, but then he could do it on his own. I do not recommend it for younger ages, unless you also enjoy making it together with the child. As for the puzzle, all Djeco products are of high quality, including this one. They have thicker cardboard than usual, which does not have a bad smell like some other puzzles when they are stored in their box for a long time. Nice box and nice design!
