Bunk beds based on the Simple Bed

I built the Simple Bed for one of our kids and now we wanted a bunk bed.  I saw many plans for bunk beds based on the Simple Bed plans, but I didn't want the ladder on the side.  I made some changes and designed the bed in 3D using Autodesk Inventor.  It didn't turn out much different than I planned.  It's super heavy, but very stable.  My wife did a great job on the stain.
