If you’re in the process of buying a new sofa, you’re probably focusing most on sofa height and width — the couch has to fit in your room, after all. But you should also consider sofa seat depth, which, depending on the couch, measures either the distance from the front of a cushion to the back, or the front of the cushion to the sofa’s back panel.
Among other things, seat depth affects both functionality and ease of lounging, which are especially important if you have kids or roommates or struggle to stand up and sit down. It’s not “one size fits all” either; just as the best sofa varies from person to person, so does the best sofa depth. Indeed, your lifestyle, age, and height could sway this number one way or another.
