I just found this cool tool on Better Homes and Gardens that allows you to design your room. First, you put in the demensions of the room you want to plan. The you can put in where the electricity outlets are as well as the phone jacks and so on.
Next you can add in where the doors are and in which direction they open. Add the windows, walls and miscellaneous. Then you can plan your furniture. They have just about everything you can think of to choose from. And you can rotate the furniture and stuff which makes it really cool.
I think this would be a great tool to use to help you decide what pieces of furniture would work the best for whatever space.
