Amber thought about this one for a moment. She raised her hand and said, "Because brooms are much more easier to navigate in the air. If you use a bathtub or a recliner, there's no way to really steer it! Plus flying carpets are illegal." She added this last part as an agreement with Miles or Tiles or whatever his name was. "Plus, wouldn't a bathtub be uncomfortable to fly in? I mean really, think about it. It's all metal and cold and stuff. A broom is much more comfy."
