What is considered the strongest knockdown joint when putting together a loft bed? I'd like to build a very sturdy and kid resistant loft bed for my son. If anyone knows of a really nice plan I can adapt please let me know that as well.
I built my daughter a loft bed. I used 4x4 posts for the corner posts and cut out dados for 2x4s to sit in connect everything. To hold the 2x4 into the dado I drilled holes and used lag bolts with washers.
On my design I put 2 2x4s on each end and 2 2x4s on one side but only 1 2x4 on the other so she can use the space under the bed.
She's 13 and I purposely overbuilt the thing so a couple of kids or her and a parent could safely be up there. It works well.
Lag bolts would probably be easiest and are typically used on college dorm type loft beds. Ultimately, it depends on your design and the spans and weights you need to accommodate.
