Hi there.
I'm a newbie so I hope this isn't redundant but I couldn't find direct reference to these articles:
[url=http://www.zafu.net/sleepergonomics.html]sleep ergonomics benefits of sleeping on hard surface soft beds bad for back[/url]
[url=http://www.sciencenews.org/sn_arc99/9_25_99/bob2.htm]Slumber's Unexplored Landscape, Science News Online (9/25/99)[/url]
Just wondering what the thoughts were on going "mattress-less" and if it even matters.
Thanks!
