Using a vintage object for a coffee table adds a bit of history — a story — to a room, and is one of my favorite things to do. Make sure the piece is stable and all the connections are secure. If you need to refinish the piece, ask the vendor precisely what it’s made from, as this will help in the refinishing process. Another consideration is how it will sit on your floor or rug, and if it will damage those surfaces. Splintered table legs or rusty metal bases can scratch or stain the flooring. Secondhand stores sometimes leave those areas unrefinished, so be sure to check.
