Breakfast by the window
Try a different seat before moving the furniture.
Use what is already there
If a chair or small table is near a window, test it with an empty tray first. Check whether the surface is stable and whether you can sit without leaning awkwardly. Keep the usual route through the room clear.
Notice the practical details
Look for glare on a screen or page, a draught, and enough room to put a cup down. The nicest view is not always the most comfortable position. Try the seat on an ordinary morning, then decide whether you want to make it a regular place or enjoy it only occasionally.
