The frame is well put together.  Solid with good support underneath.  I had some trouble attaching the middle bar on the headboard, the one that runs vertical.  It's labeled as piece 14 on the instructions, and you attach it through the slats on the headboard using 1" wood screws (part L on the instructions).  Screws weren't long enough to secure the piece, so I picked up some 1 1/4" screws, was very cautious about driving them too far through.  That worked out with me driving them close to all the way through.  Look forward to having this bed for a long time.  Will update as needed
