If you must assemble any significant quantity of Ikea furniture, do yourself a favor and ignore the tiny and disposable circular wrench and allen key they include in the packaging. Spend a few more dollars to get yourself one or more of the Fixya 17 piece toolkits. It doesn't look like much but the tools are more than sufficient to assemble any furniture that Ikea sells. At the very least you won't tear your hands and wrists to pieces trying to use those tiny wrenches to assemble anything you plan on using every day. You'll also get the job done in roughly half the time.
