I'm new to this site and I love the title, "less wrong". As a ergonomics trainer, I can identify with the "less wrong" concept vs bio-mechanical perfection which, is usually unobtainable in the average (even above average) workplace. That said, I see a number of people taking exception to the idea of "working in bed". I would absolutely agree that routinely working in bed is just plain inadvisable whether one thinks this is ok or not. Good ergonomics is as much about breaking bad habits as it is about adopting new ones. This is a good example. I also wonder about memory foam. I once thought this was a great idea and found that it was not the cure-all that I thought it would be. I think it may be a matter of preference but, that's also what people used to say about water beds. We now know that water beds are probably not good for you. I suspect memory foam mattresses may eventually fall into a similar category since they tend to negate the body's natural positional changes throughout the sleep cycle. Don't get me wrong, memory foam has it's place such as relieving pressure points if one has to stay in one position for long periods (like the the apollo astronauts sitting in their cramped space capsules or bed ridden individuals). Well, that's my two cents worth.
