The frame and all the corners should be well padded. Run your hand over them firmly to see. A padded frame will not stick out through the upholstery, it also means less friction for the fabric that is covering the frame. Check the sofa from behind, and pat the center to make sure it isn't hollow.
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.
Just as in well-tailored clothing, patterns and stripes should match at the seams. Although it might not catch your eye right away, mismatched patterns or stripes will give you the sense that something is"off". Stripes that match at seams make a sofa look well finished. Patterns should be centered, and all seams and welts should run straight. Uneven welting and seams that are pulled to one side or another mean that the cover was badly tailored.
