Within our homes we have pieces of furniture which are purely functional and do not serve any real aesthetic purpose, they are just in our homes to serve a purpose. We don't really think too much about these pieces of furniture and neither do our guests. Sometimes these items of furniture can be quite nice pieces but they might just lack something to set them off, and this thing to set them off doesn't have to be anything too spectacular. Maybe an ornament would do the trick, but cheap ornaments look exactly that, cheap. A bowl of fruit or a water feature is a possibility but they are a bit old hat now.
The coffee table should be suitable to your living style. If you rarely use it, possibly only to serve your guest a cup of coffee, choose a small, simple table. If it is likely to get used as a place for your favourite magazines, flower vase, bowl, etc., then go for a spacious table with drawers. To show off decorative accessories (shells, stones, photos, etc..) choose a table by the window. For a small space, choose the set of two or three tables of different sizes, which usually is stored underneath one another, and occasionally, when the situation requires, all three tables can be used.
