So far this is the best bed I've ever owned. I hope it holds up well & time will be the test of that. It appears well constructed and very solid. Sleeps like a dream, as they say. I really like the zero G position, as my feet tire and it really helps. The manual that came with it included a reference to parts that this model no longer used, so they really should match or update the manuals that get sent though. It was very confusing. The connectors they mention don't seem to exist anymore on the later versions of this bed.
