I think the issues are product liability, and financial. You have to pay to get a cookie pop up advertising spot. And, of course, something constructed of wood is potentially more likely to cause an injury than the swap blocks, and the qb would not want to be held responsible in any way. I still think it's a great idea. I could see one in my family room right above the heater. Then when dh gets cold, has very thin blood, he could pull a heated quilt down, and warm up. Sounds good to me!
