Choose your fabric wisely since people may want to put up their feet (and shoes). Outdoor fabrics can be smart; steer clear of linen and fabrics with high amounts of rayon or viscose. Take a swatch home and test it out with dirt red wine or whatever you think your coffee table will encounter to make sure your fabric choice can handle it all. Keep an upholstered ottoman 18 inches from a sofa or chair so you can easily put up your feet and make sure the height is consistent with the surrounding seats.
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.
