Furniture for your Room!
Yesterday I purchased a couple of chairs to fill some space in my room. I only had one twin size bed, so there wasn't really anywhere for my friends to sit when they came to visit. These were a perfect solution. The types that I bought were the butterfly chair (doesn't actually look like a butterfly), and the moon chair (kinda does look like a moon actually). You can get them in a variety of colors, but the ones I got are just plain black. I thought I would keep it simple and classy.
A futon is also a great idea. Many of my friends have these, however they can tend to be quite expensive. If you look on sites like Kijiji or Ebay then I'm sure you could find one for pretty cheap.
