Loss of air in an Air Mattress...no holes!

Question

I have had this issue with every air mattress we have used camping. You inflate it and come morning, your sinking down almost to the ground. People say it is because the once hot air cools and condenses inside the mattress. There are no holes in the mattress. How do you suggest keeping the mattress firm all night?

Answer 1

Get a foam pad.  Therm-a-rest is best (most expensive too).

Air doesn't condense.  (At least if it does, you've got bigger problems (like breathing) than your mattress).  If the air is warm it will lose volume as it cools, so blow up air mattress early enough to let it cool, if possible.  Are you sure there're no holes?  Have you checked the stem.  Air mattresses I've used (in cottages) have never been a problem.

Answer 2

Here is a suggestion get a sleeping bag or a cot that away you won't have any problems  and you will really be camping then

Answer 3

Lol...I'm with you on that one!  It's stretch...it has nothing to do with hot air at all.  The plastics used to make the mattress will stretch when you lie on it when it's fully inflated, thus creating more volume and making your **** touch the ground.  When you deflate the mattress the plastics will "shrink" back to their original form, so to speak.  Unless your using your mattress for more that 2 or 3 days consecutively, you'll always have this problem.  I always like to inflate the heck out of mine initially so that when it stretches it'll still be somewhat firm.  

Answer 4

Over  inflation often causes tiny smaller than pinholes where the baffles in an air matress connects with the top and bottom of  matress. This often causes very slow leaks. If you prefer air matress over foam pad, buy a good quality one and be careful not to over inflate.
