As much as I find the bed discussion more interesting than Bob saying he wants to glass the mayonnaise ghouls for the thousandth time, the bed is actually made of different parts that fit together and not one solid piece of furniture as everyone seems to be thinking it is.
You can see how the bed works here (Aliexpress link, but the video showcases it nicely). This bed in particular seems to be a 2017 model from the Chinese brand "Di Yu Xuan" and is not exactly the same as the one in the image because it's a customizable product.
For cleaning or making the bed you'd just detach the sides and lower part and do as you would with any other, then roll those parts back into place after you're done. If you're worried about waking up in the night or moving in your sleep you can keep the parts away and only put them back in place once you're awake.
Now back to Bob's impotent rage and Chris shilling his podcasts to the uncaring void.
