A lot of guys cannot get past the thought of a giant television when they think of furniture. There is actually a little bit more to it than that, although entertainment is very important.

You want your furniture to be comfortable. After all you will spend a good amount of time siting, laying on or otherwise interacting with it. So comfort is the most important thing. You also want to use what space you have in the best way possible.
