SAN ANTONIO - Outrage is building after a San Antonio mattress company aired a “Twin Tower sale” video, days before the 15th anniversary of the deadly attack that killed nearly 3,000 people. The 20 second Miracle Mattress video opens with three people standing in front of two stacks of mattresses. The advertisement says mattresses will be on sale for the price of a twin mattress. Two men are then “thrown back” into the two stacks of mattresses, causing them to fall over.
