Sofas and chairs are definitely the stock components of a full time income room. Sofas in particular 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 varieties of functionality involves an additional cost, so you should choose wisely. For example, there is 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 the type of living room furniture you want to purchase should be determined first by your own specific needs.
