One thing to consider for any airbed pumped up during day, warm air expands and cold air contracts hence beds going soft at night and towards morning.
Absolutely! I think this is something many people don't consider, especially when using airbeds (any type) in warmer climates.
Years ago, we took our aerobed inflatable sofa to the south of France, got back one afternoon to find it had twisted out of shape in the heat. Even after letting some air out, the next morning it was saggy and - we thought - had deflated. We then twigged it was all due to the differences in temperature and why our airbeds needed topping up every morning, despite being pumped up firmly before we went to bed.
Nowadays, we use Thermarest SIMs, so have no such worries. They were a bit on the expensive side, but totally worth it. Not only do they not deflate (or expand!) but neither do they cause us aching backs.
