I ordered an inflatable queen mattress with built-in pump from SoundAsleep, but it leaked so they sent me a new one. They didn't want the first one returned, so I tried to patch it up.

I successfully patched the leaks, but just inflated  it and now it leaks again. I've never used it except to test it for leaks.

SO: It leaks. But it's free. If you want it to try to fix it it's yours. You can see some of my patches in the photos.
