Mirrors flanking a bed do something no lamp can. A bedroom is lit at night from two or three low points, and most of that light is absorbed by walls, bedding and a dark headboard. A pair of mirrors set at eye level above the bedsides catches it and throws it back across the room, so the same lamps produce a noticeably brighter space. It is the oldest lighting trick in interior design and it predates electricity by centuries.
Oval is the right shape for it here. A rectangular mirror at that position repeats the lines of the bedside chest beneath it and the wall around it; an oval breaks them, and it echoes the arch of the headboard rather than arguing with it.
Our master Indian artisans carve the mirror frames from the same drawing as the bed's shoulders, so the scroll that turns at the top of a mirror is the scroll that turns at the top of the headboard. That is only possible when the pieces are made together - which is the practical argument for buying a room rather than assembling one.
