Need to swap out the light bulb in the ceiling fixture? Or have you finally mustered the energy to clean the upper kitchen cabinets? Either way, unless you're taller than the average basketball player, the situation calls for a step ladder. It's the sort of household essential many never think to own—that is, until the moment when it would really come in handy to have one. Conveniently, the two-step model shown here folds down to mere inches, making it a cinch to store in the closet or anywhere else you have a sliver of space. Available at Home Depot; $15.88.
