An off-center window does not have to dictate an off-center bed, and it does not always need to be disguised. Separate the practical decision about bed placement from the visual decision about the wall behind it.
Position the bed where access, door swings, and storage work best. If that leaves the window to one side, accept the arrangement provisionally. A comfortable route around the bed is more valuable than centering it on a window while making one side difficult to use.
Decide which line will organize the wall
The bed and headboard can form the main center, with the window treated as a separate feature. In that case, use bedside furniture and lamps to support the bed rather than trying to mirror the window. A broader artwork or a taller lamp on the quieter side may balance the visual weight.
Alternatively, the entire wall can become the reference. A generous curtain treatment may connect a small off-center window with the rest of the wall, but do not pretend the glass extends where it does not if that requires awkward hardware or blocks necessary access. Measure the available mounting area and keep coverings clear of heaters and operating parts.
Use asymmetry deliberately
A small table on the window side and a wider nightstand on the other can be appropriate if the room's space differs. Similar heights or finishes can make the pair feel related. Do not fill the quieter side with several small ornaments just to compensate for the window; one clear element is usually easier to read.
If the window sits partly behind the bed, check ventilation, opening, covering operation, and any required escape function. Keep furniture placement compatible with those needs. Where children live or visit, follow window-covering safety guidance and choose cordless controls.
Look at the evening version
A window changes character after dark, while a lamp becomes more prominent. Check the balance with the curtains closed and the lamps on. You may need less visual weight on the opposite side than the daytime view suggested.
Try a photograph from the doorway, then spend time in the room. A slight asymmetry often becomes unremarkable once the furniture works well. The aim is a wall with an understandable composition, not an elaborate attempt to make the architecture look as though it was built differently.
