We've always found the Vika system, Ikea's make-your-own-table array of interchangeable tops and legs, to be a great product line for people who move a lot, and for those of us who live in small spaces and need flexibility in their furniture. We've also always thought that Vita's table leg options, which are mostly wood, were a little limited considering the many uses that creative people find for such versatile components: not just tables and desks, but also office or kitchen peninsulas, counters, even a changing table top to float above a dresser. So we are delighted to have stumbled upon steel furniture leg components from Mockett, a specialty hardware maker in SoCal. Mockett expands the options considerably with a wide range of shapes, weights, and specialty functions like adjustable height (electrically-driven or not), wire management, and casters. We especially like the double-angled Lucy, the classic and clean-lined Parsons, the reto-looking Wishbone, as well as many more standard industrial metal shapes like oval and square. Mounting systems vary considerably with the leg design. Lucy, for instance, mounts onto the table top of your choosing with three screws. The square legs have a flat mounting plate, offset so that you can attach them to the very corners of your table top to achieve a Parsons-like brevity. Each model has downloadable specifications with exact meausurements, so you can plan before you order. Prices range from $57.50 to $304 apiece, here.
