Would you consider building a closet that would hold the platform on which your mattress would be placed? The outer side of the platform could have drawers or doors to the storage units under the platform. This kind of enclosure would work better for a twin bed than for a double, but it would provide a place where the bed can be concealed during the day time. Then, if you could allow a path between the bed enclosure and sofa, you could have the sofa face the dining table, or you could place the dining table at a right angle to the end of the sofa.

Ganesh, your question is very open ended . Please provide your floor plan and pics .

I agree that your small room can look beautiful. Your floor looks clean, and it is obvious that you wash laundry. Wash your shelves and dry them with a cloth. If your clothing will not get mildew, fold it neatly or roll it (fewer wrinkles) to store it on your shelves. Stack your books and papers neatly - either flat or vertically, depending on the moisture/humidity level of the air in your climate. I see that the wooden bed and another piece of brown wood furniture might benefit from some cleaning followed by an application of furniture wax. I see that the pink base for the desk/table by the bed would benefit from wiping with a damp cloth. Wipe off all surfaces of your chairs. I see that the wall near floor level is discolored. Find out what might be done to clean this. You can make this room clean and beautiful! Best wishes for success.
