Attic bedrooms don’t tend to have many storage cupboards or wardrobes, so it can be really useful to add hidden storage. This gives you places to put all your things and helps to prevent the room from looking cluttered. Consider installing a window bench that doubles as drawer space, or look for a bed frame with drawer space built underneath, or install a free-standing wardrobe. If you are on a budget, consider purchasing kit-set furniture to reduce the cost. Adding a chair to your room can help to create a separate space within the room. Utilise the chair as a reading nook, a place to rest clothes, or as a feature piece. Choose a chair that is comfortable and expresses your own personal style. Armchairs are great for reading, simple wooden chairs are good for hanging clothes, and peacock chairs are great feature pieces. The vertical poles on canopy beds help to accentuate the height of the room. Choose a canopy bed with soft, draping fabric to help promote a calm and relaxing ambience. Place the bed in the highest part of the attic room to maximise the ambient and lengthening effects of the  bed. Purchase a canopy bed from a furniture store or online. The human eye tends to find symmetry calming and aesthetically pleasing. Place matching bedside tables on either side of the bed to create this effect. These are also useful for storage and displaying small ornaments or plants. Opt for bedside tables that match the rest of your furniture. For example, if your headboard is made of dark wood, choose bedside tables that are also made of dark wood. Aim to have your bedside tables at a similar height to your bed. This looks nice and makes it easier to reach the items on the tables. If your attic only has one or two windows, arrange your furniture so that the natural light will rest where you spend the most time. Most likely, this will be your bed; however, you could place a desk or chair in front of the window to catch the light instead. Natural light helps to give your room a warm, cosy, and fresh atmosphere. Watch where the sun falls throughout the day. If you spend the most time in your room in the mornings, check where the sun falls in the morning.

Summary:
Add storage solutions to help make the room functional. Place a chair in the room to create a cosy getaway spot. Try a canopy bed if you have high ceilings. Add bedside tables to make your room look symmetrical. Place your most used furniture in sunny spots.
