I purchased these baskets to use as storage for my toddler's small toys in an entertainment center. Needless to say, durability is a top priority. [...] The fact that they fold down, however, does not affect their strength.  These are strong baskets!  My toddler has "tested" them by sitting on them, and they survived it. (I obviously don't encourage that, however.)Overall, these baskets are a great value for the function they provide--and they look nice, too!
