Whether it’s your go-to spot at the end of a hard day or more of a focal point for a formal setting, figuring out how you intend to use your sofa is essential. The greater the inside seat depth, the cozier the sofa is, as a general rule. If you’re on the taller side, enjoy csluging up with your feet under you, or cuddling with your pet, choose a deeper seat depth of 24 inches or more. For those who prefer a formal sofa style--sitting upright with the feet on the floor--a seat depth of 23 inches or less works well.

One of the essentials for finding a great sofa for your living space is one that people tend to forget. Overcrowded furniture layouts cause poor traffic flow, inhibit a room’s functionality, and create safety hazards. They also prevent relaxation. Allow for at least 18 inches between the sofa and the coffee table, and at least three, but no more than 10 feet of space between the sofa and other seating in the room. The room won’t feel crowded, yet will allow good conversation flow and won’t interfere with foot traffic.
