If you're hunting for the perfect sofa to nap, lounge and roll around on all weekend long, go for the couch with a depth of 36 to 42 inches
. (But be warned: You must measure every hallway, doorway, corner and stairwell that the couch needs to pass through to avoid the furniture not fitting
.) Shoppers tend to overlook the extra-deep couch option and go for the more conservative option, with a 29- to 32-inch depth, Laurel & Wolf
designer Kimberly Winthrop
says. "Some people sit in it and think it's too deep, but that's where you've got your lumbar pillows and decorative pillows," she says. The most important thing to consider, when it comes to extra sofa depth, is a person's height and body size. "I am 5 feet 6 inches tall, and a 38- to 40-inch sofa is very comfortable to me. My clients that are in the 6-feet height range like a sofa in the 40- to 42-inch range because they have longer legs," she says. For the coziest and most durable material, go for 100 percent polyester, the performance fabric, which feels like a linen and is nearly indestructible.
