The floors of your home, garage, or office can make all the difference in the world when it comes in regards to overall appearence. Furthermore, choosing the right flooring can benefit you in more ways than you know... switching from carpet to tile can help your allegies, for example.
Last year, I pulled up my old carpet and switched to tile because I have pets. This made a huge different. I did, however, keep carpet in my room -- I'm thinking of switching to hardwood floors though.
In any case, I reccomend that you take your time when choosing the type of flooring you plan on using in your home because it can truly make all the difference in the world.
