How can I plug a leak in a very large air mattress?

We have a very large air mattress - queen size, double height - that sprung a leak. It was very slow at first, but now it's far worse ... you're down in a big sink hole by morning!

I think it's really too big to try to figure out where the leak is and patch it with a vinyl patch. (Already tried to find the leak - couldn't.) Anyone have experience with other products? Something like Fix-a-Flat that I could spray into the air nozzle?

I should have said - I am aware of how you should proceed when trying to find the leak, and I do have a patch kit. I've done the water and bubbles thing. Can't find the leak.

I stress - this thing is HUGE. It is 20 inches thick (the size of a box springs and mattress combined) and queen sized. There's no way you're going to get this thing into a tub or something - even half inflated. It's more like a big bed that happens to inflate.

Off-gridder,

If the hole is that large, you should be able to locate it without too much trouble. I'd let it deflate until it had just a little bit of air, then submerge it in the bathtub. The bubbles will quickly tell you where the hole is located.
It's kind of difficult to figure out the proper fix, until you can determine the exact size of the hole. Nowadays, companies that produce these mattresses offer some pretty large patches. I patched my mattress with a company provided patch that was transparent, and looked more like fly-paper than a patch. I worked great.

good luck

You should really take the time to find the hole. Try by using a spray bottle to spray water on it and see where you get a bubble. if you use the fix a flat and it doesnt work good then in time the hole is going to get bigger. Just try to find the hole again.
