What?! My bed's in the sky, it's so weird that this one is on the floor. The floor! Of all places!
It's probably plausible, but you should use "Står" instead of "Er." This is because "Står" indicates position, and "Er" indicates any other reason why you'd say "Are."
In a truck if you're moving, in a cage if it is for a pet, in the washing machine if you're cleaning it, in your hand if it is from a dollhouse you're playing with, etc. I agree a lot of these sentences seem funny, and are usually not anything I think I would use, but they are not always as "odd" as they may seem at first.
Stand, but it can also be translated in English as "is" because sometimes it doesn't make sense to say eg. The bed stands on the ground
