To preserve the adjustable air mattresses usefulness, it is necessary to conduct at least a monthly inspection and check up of their condition. Since these are rubber-made air mattresses, it would be prudent for you to inflate them at least once a month, so you can check if leaks have developed during the time of the storage. An air mattress that leaks and cannot hold air at the time of use can be most problematic, especially when you are already out in the field with the family. You will be bothered no end if a kid or two of yours have leaking air mattresses when they already want to use them.

Rubber-made portable air mattresses tend to have molds develop within the folded parts and the molds sometimes is the cause why the leak develops. Some insects also might have something to do with the leaks developing while the mattresses are stored in the dark attic.

Since you will need to inflate regularly the adjustable air bed mattresses as you check them up, it will be good for you to have a portable air pump, even just manually operated, to facilitate the filling up of the air for the mattresses. When you have filled each air mattress with air, try to submerge each of them in your pool if there are air bubbles coming up from any point in the mattress. The source of the air bubbles are the air leaks that you can detect because of the air bubbles. Other wise if you do not submerge the mattress in water you would not have noticed the very small leaks.  

After you have marked the points that are leaking, take out the mattress and dry it thoroughly in the sun. Be sure they are dry since you will be using some rubber sealant materials that may not stick effectively on a wet surface. You can repair the leaks without any problem with the rubber sealant, provided you follow strictly the application procedures prescribed in the product’s use.

After you have done the repairs, you may want to do a second testing by filling up the defective mattress again with air and submerge it in the water for the second time. This should confirm the effectiveness of the repairs you have done, otherwise if there are still air bubbles coming up, you have to do a repeat of the procedure you just did for the unchecked air leak, this time taking more care that the leak is finally sealed effectively.

These maintenance activities needed during the months of non-use of the air mattresses that you have in your attic may sound a bit tedious, but it is good exercise for you in the weekend that you have designated as the air bed mattresses maintenance weekend. It should be a good break from the regular routine in your office. Above all, you can be sure you have good air mattresses when it is time to use them.
