An end table is a table that is placed at the "end" of a piece of furniture. Yes, it really is that simple. For example, you might place an end table at the end of your sofa between it and a wall. End tables are typically smaller than side tables (approx.12" - 18" diameter/square) and can often fit into tight spaces. Here are a few examples of end tables that pack a lot of styles and would work in many modern contemporary or transitional spaces.
