There is something comforting about crisp white bed linens. They feel clean and fresh and literally resemble fluffy white clouds that invite deep sleep. But, a classic white bed can also be boring if not placed in the right design context. Dark walls provide a stark contrast that make white bedding look sophisticated and even bold.
There are practical reasons for white bedding that can rival its aesthetic appeal. If you're not afraid of using a bit of bleach, almost any stain can easily be erased with just one wash.
Also, a big white bed in the middle of a darker room can make a space look larger than it really is because the lightness draws the eye to the center of the room while the walls seem more recessed. Not to mention, darker walls can create an intimate and enclosed space that is more conducive to sleep than a bright bedroom. Although, this look probably works best in a room with ample light. There is certainly an incentive to avoid a bright light in the bedrooms of those who like to sleep-in beyond sunrise.
