Buy a sofa with style that matches your own. If you are more traditional, choose a sofa with rolled arms and tufted cushions, like this one from Vaughn-Bassett. If you lean toward contemporary, choose a sofa with cleaner lines and understated upholstery. If there are other skirted pieces in the space, choose a sofa with exposed legs and vice versa. If you’re short on space, look at sofas with low arms, or no arms at all, to make your room look bigger.
