Oftentimes a sofa seat will have just a single cushion. This is also called a bench seat. A single-cushion seat offers a tidy, minimal look but also can be combined with a pillow back, which is more about casual comfort than minimalism. When you sit down on one end of a good single cushion, it will not rise up on the other end.
Also called a box arm, a square arm gives has a modern, tailored look, with straight lines and angles. Square arms are useful for entertaining, as they can serve as seats. However, they are not as comfortable as rolled arms for lounging. Tuxedo arms are slightly flared arms that have the same height as the sofa back.
Anytime you´re arranging furniture you have to think about balance. When too many visually heavy things are on one side of the room the entire space looks unbalanced. Since sofas tend to be large in scale they take up quite a bit of visual space, and they require something of equal weight across from them to balance out the room. This is why you often see two chairs placed directly across from a sofa. Together the chairs balance out the weight of the sofa.
