Buying a couch for my room?

I want to buy a couch for my room, like a soft suede-ish material. Im a 14 year old girl so of course i like soft things. I want it to be like average sized, not small. Preferably purple, or a cool design or something. Links would be nice, and websites that sell like nice teen furniture. i don't want it to be too expensive, like max 400 dollars. Thanks!
