Hi r/DIY! Got a bed frame squeaking problem that I'm looking for some tips on. I spent the better part of an afternoon last week trying the standard stuff - Took it apart entirely and made sure to tighten all the bolts and waxed all the contact points. I THINK most of the problem is in the slats, which connect to the bed frame via wood joinery, with a sheet of plywood sitting on top of them.
The bed itself is a mahogany (I think) four-poster style frame, and the frame elements are connected by brass bolts, with slats that fit into the frame via wood joinery. One of the upper horizontal members is missing from the assembly currently, as one of the brass bolts snapped in the process of moving a few weeks back, so I'm sure that'll lend to some flexing issues until I get around to getting a new bolt.
Anyways, is there anything else I could try to help curb, if not silence, all the squeaking? I was considering buying some foam to put between the plywood and the slats, but I'm not sure how much it would help if the slats themselves are possibly flexing and pushing/pulling against the frame. Alternatively I was thinking about sanding the ends of the slats down a hair to reduce the amount of compression they're under, but at that point I'm not sure if that would worsen the problem by giving things more room to shift around. Here's a photo of the bed itself and a shot from underneath of what the slat connection looks like with a crappy plan diagram:

I’ve always used soap on all wood to wood contact points, but your wax should do similarly.
