I love a good fireplace, but I hate having to move away from it to make myself a sandwich or use the bathroom. That's why I love this rolling fireplace: I can roll it around with me wherever I go.
Sure, if it tips over or goes down some stair accidentally you might just burn your house down, but come on. You're not some sort of klutz. I think the possibility of imminent danger makes this thing even cooler, anyways.
