Ok, I incorporated a few ideas from last time in the latest update of my bed (cherry) project.
I designed the curve from the slats into lower footboard rail. The footboard and headboard cap will have a round over (1/2" radius) that should make it safer. I have a question on my blog that will make more sense after you see the renderings.
Comments welcomed and encouraged (either here or on my blog is fine)
