Last fall, the slats on my bed frame started giving me trouble. One or two would slip off the lip of the bed frame, causing the mattress to partially fall onto the floor. Naturally, this only ever happened at convenient times when I was definitely alone.
Eventually, I figured out that, if the slats had a little less room to slide around, they wouldn’t fall anymore. The solution? A 10 cent bic pen slipped between the rows of slats (see picture.) I steadied three sets of slats with pens, and haven’t had any trouble since.
