Nope! I suspect he built those for himself -- unless someone buys them.
I must speak to him about building something to fit between the two beds. I need a place for the clock, and other needed items. Since Spouse prefers to move the beds together as close as possible, it must be light as well.
Poor baby, Spouse has fallen out of bed 5 times by slipping between the twin beds. I've found that if I swing my arm and my leg over to his bed, it works to keep him from getting too close to the edge. Not all that comfortable, but effective.
