I'll start with two examples of what I don't want.
Two years ago, we bought a double Kathmandu airbed in some camping shop in New Zealand. It wasn't cheap, and it was really good for a month of camping. But then ... this year, while camping, we were unpleasantly surprised with a big bulge in the middle of the bed (inside seams broke?). The bulge then expanded through pretty much whole bed.
We have another Intex airbed at home for a spare bed, which is slowly leaking air.
None of these issues are apparent when you're buying, and reviews seem to be good for pretty much any airbed. Recommendations that I find online are very generic (e.g. heavy and comfortable when close to home, light when travelling).
Is there a sane way to pick good airbed?
