One point to clarify. The cushion portion isn't detachable. It's one of those contemporary style sofas that look like it's a cushion, but it's really attached to the rest of the sofa and cannot be removed without disassembling the entire fabric from the sofa section.
Something alone the line of this, though not exactly.
Thanks for the suggestions thus far. This is one more issue i can add onto the my growing list for 2008. Frankly I'm more peeved at my nanny that was suppose watching my daughter as my wife is away on business..Not because of the sofa was destroyed, but because there shouldn't have been any reason why my daughter would have been left alone for that long to doodle that much. The damaged couch is replaceable in worst case, my kids safety is not. I guess worst case, I can just have my daughter doodle on the rest of the sectionals and make the sofa look REALLY contemporary.
