So the wife was surfing around the interwebs and found this bed, and wants me to build one similar to it.

Attachment 251388

So it will be made out of QWSO, assuming I can find a local source of 16/4 for the posts. I guess my main question would be if the mullions should just be applied over a plywood back to simulate the look, or would I be better off going the more complex route of structural mullions and individual panels?

Additionally, the side rails connecting the headboard to the footboard will need to be wider so that they can keep our two twin sleep number mattresses from separating.

I have been trying to learn SU, but I don't really have the time to devote to it, so I am sticking to pencil, paper, and scale for now.

I appreciate any help,

Mike
