When you're choosing pieces for any room, but especially one with tight spaces or an unusual shape, the Henredon Room Planning tool can be a huge help.
You just enter the dimensions of the room, including any alcoves or nooks, add the doors and windows or any other features like fireplaces. Then, you can choose Henredon pieces to place in your floor plan. The dimensions of all the Henredon pieces are entered for you and you get little outlines showing just what you need. You can figure out exactly what will and what won't fit in each part of your space.
I did a little floor plan of my bedroom.
It's a floor plan challenge because I live in a city apartment and space is somewhat limited. Plus, a lot of my bedroom walls are taken up with two large windows, two doors to other rooms, and a closet door.
