You try to figure out the word with my Hints.

First Hint:

My first teapot is not a place where you should lay down
My second teapot is a place where you could lay down, but without any reason that's quite strange
My third teapot is part of a place where you normally lay down

Second Hint:

My second can move normal
If someone sees my third teapot moving please send me a pic

Final Hint(makes it really easy):

Answer

I feel I'm way off, but is it a

Wing (Bird wing, wing, a unit of military planes, Wing of a building)

My first teapot is not a place where you should lay down My second teapot is a place where you could lay down, but without any reason that's quite strange My third teapot is part of a place where you normally lay down

you should not lay down on a bird wing! If you are flying as part of a military wing, you probably won't be laying down. Your bedroom, however, might be part of a wing of the building

My first teapot can move up an down My second can move normal If someone sees my third teapot moving please send me a pic

Bird wings flap, military wings move normally, and building wings generally don't move

My first teapot is assumed soft but is actually pretty bony My second teapot sounds just soft On my third teapot soft can't be applied

Bird wings are bony, Military wings...er.. don't sound soft, soft isn't a word associated with part of a building

And the final hidden hint

Bird wings allow birds to fly, military wings also fly, and buildings can't fly.
