When one person is higher up than others, it can make people feel towered over and uneasy -- even if it's just on a subconscious level. Make your living room more comfortable for visitors by offering seating options that are of similar height.

This might seem like something you shouldn't have to think about, but if you bought your couches and chairs at different times, comparable seat height probably wasn't on your mind. Don't forget that even if seating is around the same height, people may still feel uncomfortable if they sink in (and thus lower their point of view) to your couch or chair.(Bar stools are another common culprit.)
When people visit, you want to make your home as welcoming as possible, and this is one simple place to start. For more advice on improving your living room, check out the post from Apartment Therapy linked below.
