There’s a lot of furniture today that’s not built for a second life—it’s not structurally sound enough to invest in. If you have a piece with a well-made frame, it’s probably worth it. Older furniture tends to be higher quality—something that was your grandmother’s in the 30s or 40s is more likely to have dowel joints than be glued together. That’s worth investing in. It’s a time- and labor-intensive process that involves specialized skills. A well-done job can include stripping a piece to the frame, reinforcing the frame and the joints, replacing coil springs and zigzag springs—and that’s all before the cost and complexity of fill, padding, and fabric. The most common misconception is that reupholstering is just about fabric. There’s a huge difference when it comes to price. A down-and-feather sofa cushion costs about $650; foam could be $75. Down is very comfortable, but it compresses fast and doesn’t hold its shape for long. It needs constant refluffing to look good. That’s why a combination is so popular: A foam core with a down-and-feather wrap is soft and keeps its shape. This is important. For both seat and back cushions, the ratio should be about 60 percent down to 40 percent feathers. A too-high percentage of feathers is bad—they’ll poke through the fabric. If you’re not sure what percentage your existing cushions have, unzip the covers and read the tags. Cushions could be labeled “down and feather” and actually have a ratio of five to 95. If you replace your cushions, ask the upholsterer for 60 percent down and 40 percent feathers. Unfortunately, dogs love every kind of fabric. In my experience, though, cats don’t like mohair, and they stay off it. As for kids, I have two—and, yes, upholstery is going to get damaged with little kids around. There’s no way to avoid it. Get a bunch of bids. If you’re hearing $3,000 from five places and then someone says $1,200, run the other way. That’s what I call a chop shop. They’re not going to do a good job. No matter what your upholsterer tells you, wash the fabric before you have slipcovers made. I promise you: It will shrink massively. Otherwise, the minute you take the covers to be dry-cleaned—which involves liquid—they won’t fit anymore. And if the upholsterer says you need 10 yards of fabric, buy 15. The main thing to pay attention to is the spring action. If you hear an eee-eee-eee noise when you sit down, that’s not good. And it will cost you. Avoid two-tone upholstery. Like a sofa where the front and the back are different colors. You might be sad that you did that in a few months. If you want to take a big design risk, do it with throw pillows. Keep the sofa basic. Sometimes people come to our studio wanting to preserve things for purely sentimental reasons. And that can be perfectly valid. In a time when so many of us live far from our families, and when so much is disposable, it’s nice to have a personal piece of furniture in our homes.
