The ideal sleeping-room is the outdoor porch with only curtains for protection. An indoor sleeping-room should have simple furnishings. Unnecessary draperies collect dust and exclude air and sunshine. The floor should be bare save for a few small, easily cleaned rugs. The wall paper should be of a soft restful color, either plain or with small inconspicuous figures.

An iron bed is better than a wooden one because it can be more easily cleaned. A mattress is more healthful than a feather bed, because the body is not so enveloped as to hinder the escape of waste matter from the skin. The bed covering should be warm but light. Several light-weight blankets or comforts are better than fewer heavy ones.
