Sofas and chairs include the stock components of an income room. Sofas for example come in many different varieties, ranging from double to four-seaters with no particular functionality to sofas with reclining features, slides and even sofa beds that are useful for unexpected overnight guests. If you elect to include them, each of these forms of functionality involves an added cost, so you should choose wisely. For example, there is very little need for a sleeper if you have a few extra bedrooms for guests, and why invest in a recliner if you never use it. Not all people like a footrest or even recline back when sitting, so any type of living room furniture you decide to purchase should be determined first by your own specific needs.
