The people on the home network will scream but you can use a chest for a coffee table.
If there is a will (to find extra storage space) there is a way. Not too long ago I was thinking about the space under the sofas. You know, that space above the floor but below the cushions. That might be some good storage for things you only need to access once a year or so. A pain to get to, but it would also keep the dog toys out from under the sofa. I also built a footstool (that was really a storage chest) for our familyroom. It is beginning to sound like I am a storage junky!
