Inquiry (采购产品): Skin Guard III repair from Lynn Caldwell, 1350 W Main St, Apt #116, Sheridan Oregon, 97378 I have acquired a used Skin Guard III alternating air mattress which seems to have a leak. The mattress slowly deflates when I lay on it, and slowly inflates when I get off. Do you have any sort of trouble-shooting guide or repair instructions and supplies that might help me? Thank you kindly.
