We have a "mattress factory" here in Fairview Heights, IL which custom manufactures mattresses and sells automated beds--no safety rails and no "trendellenberg" (moving the top or bottom up without bending the mattress) but these raise heads or knees independently. I do not know if they sell traded-ins or used beds. Their address and phone #: Verlow Matress Factory Stores 1000 Lincoln Hwy. Fairview Heights IL 622?? Phone # 1(800) 224-8375 Regards, WHH 54/18 PS: Sometimes a medical supply house will sell older hospital beds or, best of all, go to a hospital auction. There one stands a great chance of coming away with a bargain.
