Create a highly detailed and realistic background of a child’s bedroom featuring a chair designed for a school-aged child, around 8 years old. The room should reflect a peaceful and tranquil atmosphere with a calm color palette that includes soft lavender accents. Emphasize the textures, shadows, and lighting to create a lifelike environment. Include subtle details like books on a nearby shelf, a colorful rug on the floor, and gentle sunlight streaming through a window, enhancing the overall serenity of the space.
