I'm not sure the designer of this bed knows how beds work or why we find them enjoyable. When I'm in bed I don't like to feel like i'm on a cruise ship that's forty minutes away from capsizing due to an ungodly storm. This is more like a piece of Pilates equipment than a bed.
There are some points in my life where I'd rather take this bed than what I had. For years I slept on a futon that had a long trench in the middle of the mattress so it could fold more easily. My back still clicks from that. Before the futon I slept on an air mattress that would go flat after eight hours, so I'd have to wake up in the middle of the night and blow it back up. Guess how many times I got laid in those two beds? Even 0 is too high a number.
