When setting up a cozy and practical living room arrangement the key factor to consider is the spacing. It's important to leave room, between furniture pieces such as sofas and accent chairs for easy movement. Aim for about 30 to 36 inches of clearance. In spaces, a minimum of 18 to 24 inches should do the trick. Also make sure that the heights of your sofa and accent chairs are similar within 4 inches of each other, for a look and feel. By planning out the spacing you can create a balanced and welcoming living room atmosphere that enhances both the style and usability of the area.
