Convenient thing: a stepladder is always useful in the country, but it is bulky, takes a place that is never enough without it. You are looking for a nook for her, and when you need, how much work it costs to get her out of there.
Everything is convenient and compact right there: two in one! And everything is always at hand, there is no need to hide something somewhere, and then look for it. The chair can be placed in the shade of a tree and, sitting on it, read a book. And then put this chair in the stepladder, climb on it and pick up the freshest fruit from this tree.
