I hope this email finds you well. I am writing to gain feedback on the aquilla airpulse-pk cushion. According to the website, it is battery operated and automatically shifts your body weight to prevent ulcers as well as treat any current skin breakdown one may have. The cost is $3300 and I am having some problems getting my insurance to purchase the product. I have had two surgeries/flaps to correct stage4 decubitus ulcers and consider purchasing this cushion an investment worth my last dollar. In any event, has anyone ever purchased this product, do you know anyone who has it, or have you even heard about it? I look forward to your response.
