The darker coloring of dark wood material can make a room appear much smaller if not properly accommodated. Natural light is an excellent way to combat this cramped feeling. Try putting up light-colored sheers over your windows to allow natural light to shine in without leaving your windows wide open for the world to see.
Alternatively, you can try artificial lighting if your room doesn’t have windows, or if you’d rather use heavier drapes than sheers. Grab lamps that can shine a light towards your ceiling to help alleviate any feelings of cramped-ness.
