In response to a comment that air mattresses can't be expected to hold air (can that even be true?), there are now more details from Dita, on the crappy inflatable bed the Canadian Tire sold her. She certainly doesn't think much of CT!
Dita Wegman Novak It was a byob, on a stand, queen size that retails over$250. It didn't just lose a bit of air, it lost almost 3/4 of the air overnight. We also have a crappy Coleman one that just blows up and we lay it on the floor....my 75 mother loved it....and it never lost any air. In my first post I called it an inflatable bed, which I would say is different than an air mattress. Anyhow, as I expected, no comment from cdn tire.
