later on after the scratch & carve coat dries do you think it will get ruined from normal wear & tear ?

meaning the plywood flexes a little bit  it might crack the concrete possibly? or no :^)

ryan i have to say i dont think its a good idea to do the underside unless it was built to the hilt. the biggest problem here is as you say the flexablility of the ply for sure and really the 2x4s should be standing up that is where they have there most stregnth so again the flex will be highly damaging to the concrete. srry bro just tryin to help.

yeah that's what I figured :^(    so how do I , make it look like stone w/o making it look  a cheezball hack job?

well if you can really beef it up streagnth wise maybe some metal supports that run across the bottoms and hold up the ply and give you a strong foundation of boxing out the underside its important that you try not to transfer any flex from the ply that holds the matresses to your underside of the bed. if you can keep them seperated and strong im sure flex will be reduced to a min and will keep the underside structurally rigid enugh to hold the concrete with minamal cracking and your scratch coat will be very important!! as for the supports that hold up the beds as long as you really wrap the hell outta them with lath overlapping the seams and corners twice you will prob be ok. on narrow stuff its important to have an awesomely heavy scratch coat with lots of depth that will help reduce cracks at the corners.
