A window placed to one side of the bed can make a wall feel lopsided when you focus only on symmetry. The better question is whether the bed has a comfortable position and the window remains useful. A centered arrangement is not worth blocking access or forcing the bed into an awkward route.
Center locally rather than globally
Use the bed and headboard as one composition, even if that group sits off-center on the wall. Arrange the sleeping pillows and bedding around the bed's center. The window can then read as a separate architectural element instead of something the furniture is failing to match.
Keep the window covering straightforward. Extending fabric across an entire wall may create a more uniform background, but it can also conceal useful light or require more hardware and fabric than the room needs. Test the idea before treating it as the default solution.
Balance with a different element
The non-window side can carry a lamp, picture, or a slightly more substantial bedside piece if that serves a real purpose. It does not need a fake window shape. A lower object can create enough visual relationship without imitating the architecture.
Keep the bedside heights comfortable for use, even when the pieces differ. If a window limits the size of one table, give that side a compact surface and solve storage elsewhere rather than crowding the opening.
Preserve light and access
Check the window's operation, heating equipment, and any required exit route. Do not cover an inconvenient opening with a high headboard just to make the wall look symmetrical. Furniture should work with the existing room's practical requirements.
View the arrangement from the doorway and from both sides of the bed. A window that seems dramatically off-center in a straight-on photograph may barely register during daily use. Let the bedding, light, and useful surfaces make a coherent sleeping area, then leave some empty wall rather than filling every imbalance with another object. The room can feel settled without becoming a mirror image from left to right.
