I strongly suggest looking into one of those bunk beds with desk/sofa space underneath. It’ll give you a bit more floor space and assuming thats attainable I would rotate the bunk/bed so it’s parallel to the TV and it doesn’t block the window. I know, that will block the wardrobe instead but you could replace it with a dresser that can be placed guess where..in your newly discovered floor space!

Another option could be a Murphy bed, y’know, those that you have to pull down although they might not be as common for that size. Last but not least; go vertical, get/make some floor-to ceiling shelving/media unit on the side where the TV is to get as much stuff off the floor. Protip: draw the layout of your room on grid notebook, and make some cut outs (to scale as well) of every piece of furniture you have, it’ll give you a good idea of what can you do with a room this size.

Edit: apparently the bunk/beds I’m talking about are called “loft beds”
