Hil-Rom Silk Air mattress. This is a wonderful inflatable variable pressure mattress. Used 3 years by a quadriplegic who was 6 feet tall and weighed 230 pounds. Before this mattress he had to be turned every 2 hours and still got decubitis ulcers. After he began using the mattress he did not need to be turned at all and got a good night's sleep. And he never got another ulcer. This is a great skin care mattress. New cost is $10,000.00. Will sell for $3,000.00 OBO. Call Kathryn at 231 757 0557 or e-mail at kateacts@thinkextreme.net
