The bed needed some sort of support for the mattress, and I decided to use 18 pine slats to do the job.  I used a 1/2” roundover bit on the router to soften the edges, and sanded them smooth.  I laid them out on the bed, and attached them to each other in 2 sections with strips of leftover oak.  All that was left was to flip them over, and they’ll support the mattress.  I’ll probably use a couple of screws to secure the slat section to the bed once it’s in the room.
