Ok, it's not the most romantic nor regaled item on your wish list, but let's not overlook a good ladder's merits. For example, some genius added sizable wire baskets to the rungs and instantly created space-saving storage. Another creative inventor substituted shelves for treads and produced a leggy, lean-to bookcase or plant stand. Brilliant!
Still prominent today? The library or loft ladder. And the somewhat primitive and shapely wooden display ladder often used to cradle old quilts or blankets. That metal climber you bought at a big box store will never be a future design find, but the one the kids built to access the tree fort very well might.
