This is such a small project, I hesitate even to post it, but it was one I put off for a long time because I thought it was going to be much more complicated than it was.
The credenza I fashioned a few months ago from a set of storage cubes and four mid-century-style legs was not quite as well-supported as it needed to be, and when my parents were visiting a few weeks ago, Dad noticed it was developing a slight dip in the middle. He recommended I add a set of legs to the middle to shore it up.
Because I’d installed the others at an angle, I assumed I’d have to shorten the new ones before I could install them vertically in the middle — not a difficult process, but one with just enough steps to seem daunting — so I bought legs and installation hardware and promptly stuck them in my craft closet, where they remained, quietly generating low-level stress in the back of my mind every time I looked at the credenza.
A couple of weekends ago, I got sick of thinking about them, grabbed a tape measure and the new legs and installation hardware and set about taking measurements so I could trim them to the proper length …
whereupon I discovered that the designers of the legs and mounting hardware had already anticipated someone might need vertical supports on a large piece of furniture and had adjusted for that eventuality within the design of the hardware, thus obviating the necessity of trimming anything. All that procrastinating, and all I really needed to do was unload the bookcase, flip it over, and install the new legs.

I left all the books stacked at the ends of the credenza for a week or so to give gravity a chance to repair the dip that had developed while the middle was unsupported; two weeks later, it’s balanced properly, reloaded, and much sturdier. It still isn’t perfect, but it should be fine until I can score something nicer from Joybird or (’tis a consummation devoutly to be wished) Herman Miller.
Sitting in the living room feels much more relaxing now.
