When buying a sofa, the most important thing to consider is size. Be sure to measure the room and take into account angles and doorways. The next thing to consider is style and the aesthetic you’re going for. A sofa is likely the largest piece of furniture in the room and pulls the look of the space together. Consider the material when designing your room - for example, velvet adds a touch of luxury, leather is the most versatile, and a fabric sofa exudes a warm and cozy vibe.
