I was going to suggest something very similar, so I’ll just do it here. It seems that currently, mean beds are already automatically undeployed by the carpenter if ordered to make comfy beds, which I think is great. However, given that this happens, I think it would be best if the carpenter were to also place the beds back where she found them, rather than in the stockpile as if it was an entirely newly crafted item (which, I suspect, to the game, it is, currently). (That was nice with the commas.)
I think perhaps @hert’s suggestion of an “upgrade” button is even nicer (because then you can control it and can keep certain citizens you don’t like sleeping in mean beds, should you be so inclined), but that would be up to the developers.
