You should not place the sofa close to the window, especially the window facing the West. Direct sunlight over a long period of time can cause the sofa surface to fade, reduce durability and degrade quickly.
Audio-visual devices such as TVs, speakers... should also be placed away from windows because two main reasons are that the light reflected on the TV screen easily causes glare and eye strain when watching for a long time. Areas near windows are often easily dusty, and rainwater can splash into the device, affecting lifespan, and even causing short circuits.
When installing a chandelier, it is necessary to balance with the height of the room. If the ceiling is low, you should choose a lamp with a suitable size and height to avoid the feeling of crampedness. Hanging lights in the center will help light distribute more evenly. The ideal distance between the chandelier and the table is about 50-60 cm; hanging too high can easily cause glare, and too low can be a headache when moving.
The desk surface should be lower than the elbow to create a comfortable feeling when using. For multi-layered cabinets or shelves, the upper compartment should be placed at eye level for easy observation, and the lower compartment should be within reach conveniently when taking things.
