Super king beds are becoming increasingly popular, but they are only for the bigger room. You spend a third of your life in bed, so make sure that your bed choice reflects both your personal design tastes and is large enough so you can stretch out comfortably.
Of course, another aspect to a bed is its very size. Double beds (even childrens single beds) are large items. They dominate a small or even medium-sized room. It is imperative too that your bed is stylish and attractive, as well as comfortable. Nobody wants an eyesore in their bedroom, which is a highly private and personal space.
