It went pop when it stopped

Well it seems my air mattress has decided to die on me. As of 6am this morning my mattress has some mysterious leak and loses air at an incredible rate, only silently and without any breeze. Instead the air dissappears quickly from the confines of the mattress and leaves no trace of its escape route. As I haven't had time to find a replacement I get to sleep on the floor for a night. Tomorrow I need to go air matress shopping to find one that fits my bed.
