I Have a Question

whats the best way to keep my airbed from deflating at night? Ive had to get rid of my bed and couch thanks to bedbugs. ive been sleeping on an airbed cause of it, my apt building has had issues with bugs. i got the airbed on purpose cause i know the bugs hate plastic and cant nest there. i actually got rid of the bugs when i did that. but at first it didnt deflate as much but now its doing that every night, i have hip implants and cant get up if my bed would be too low but luckily its not going down that low but its still annoying, i cant blow up my bed in the middle of the night cause its loud and my neighbors might complain, there are no holes in it, at least not that ive seen, only had it 3 months, cant get a regular bed cause if theyre still in the building they'll just nest on my mattress, and yes my place has been heat treated and sprayed several times. any suggestions? im tired of having to get up in the middle of the night in a lower bed than i went to sleep in and then cant blow it back up till morning cause its loud.
